BARC 2020 exam Syllabus and exam pattern for Electronics and communications(ECE)

BARC(baba atomic research center) is a premier multi-disciplinary Nuclear Research Centre of India works on atomic and nuclear field, this is the one of the challenging work for an engineers who really interested to work in atomic field. In this post I am going to give you the complete details about BARC syllabus for ECE stream. I hope this article will helpful to crack BARC exam.

The OCES/DGFS electronics written exam paper is totally technical questions and The level of the question paper is similar to the GATE paper but not much tough as GATE. Prepare a plan to study, don’t concentrate more on studying text books, Do more work on Objective bits and concentrate more on previous papers of GATE,IES,JTO,..etc whatever previous technical question paper you have do it first, I will post more articles on how to prepare for competitive exam later on. one who works on bits can easily qualify in written exam. This paper consists of both theoretical and problematic questions. 

There is no specific syllabus given by BARC we are expecting more questions from the below topics. The exam Paper may contains 100 question (2 hours duration) only Technical questions there is no general questions. The most of the questions will come from Analog and digital electronics, electromagnetic and microwave, Communication(analog & digital),control systems, Signal and systems, Microprocessor, Computer organization,Network theory. 

  1. analog electronics: Most of the questions will come from OP-AMP, feedback amplifiers, oscillators, amplifiers, diode equation, zener diode, A-D and D-A converters. 
  2. digital electronics: K-map, Combinational( Mutiplexer, encoder, decoder, basic logic circuits) and sequential circuits(flip-flops, registers, counters).  
  3. electromagnetic: Maxwell’s equations, Electromagnetic wave propagations, transmission lines, microwave.  
  4. communications: AM, FM, PM, PCM, DM, FSK, QPSK, PAM, PPM, noise, ISI, probability of errors,   
  5. control systems: Stability, steady state response, transient response, compensators, Root locus, bode plot. 
  6. signal and systems: signal basics, system basics, Fourier transform, laplace transform, z-transform.
  7.  network theory: nodal analysis , mesh analysis, theorems(thevinens, nortons, max power theorem, superposition), two port networks. 
  8. microprocessor: mainly they will ask 8085 basics and small programs.

Practice all previous GATE questions,IES, JTO, etc... don't believe this is the exact BARC syllabus fully some what we are expecting finally i suggest you to just followthe  total GATE syllabus.

ISRO previous year question papers for electronics and commnications(ECE)

Indian space research organisation is one the center to study about the space.ISRO (Indian Space Research Organization) is to develop space technology and its application to various tasks of national and international interest.
every year they release a notification to recruit a young scientist. So to Get clear the written exam you must start preparation from now onwards.The exam paper will totally objective with negative marking,the syllabus is totally similar to GATE syllabus but some questions will also come from basic computers.

The cutoff for the written exam will changes for every year, But approximately if you get 150 marks then there is a chance of getting call for Interview.

How to prepare to the ISRO written exam:

The exam question will be like a GATE model questions.So be thorough with all the topics and practice all last 10 previous ISRO ,GATE, IES papers.No need to study in depth concepts to clear written exam because there is a less time to study so, practice all previous questions of GATE, IES, ISRO and try yourself to get the solutions to the previous questions. I  think previous question is enough to clear written exam but the chance of Repetition of the questions is very less, they may ask similar models as in previous questions so, practice all the questions clearly.

Mainly concentrate more on weightage subjects like ANALOG CIRCUITS, DIGITAL ELECTRONICS, ELECTROMAGNETIC FIELDS, COMMUNICATIONS,ANTENNA BASICS.  their is a chance of getting more questions from these subjects.

ISRO EC syllabus for electronics and communication-ECE 2020

ISRO Scientist-B recruitment exam syllabus 2020:

In this post, I am going to discuss the latest ISRO ece syllabus, which is useful for your preparation of upcoming ISRO scientist-B exam.

The syllabus is similar to ECE GATE syllabus,we should prefer GATE and IES electronics syllabus for any competitive exams, In ISRO written exam, some questions will be asked from computer engineering which is not in Gate syllabus, here I am giving basic syllabus based on previous papers,You can also see the previous isro papers here.

(1) Electronic Devices and ICs:      
Energy bands in silicon, intrinsic and extrinsic silicon. Carrier transport in
silicon: diffusion current, drift current, mobility, and resistivity. Generation and recombination of carriers. p-n junction diode, Zener diode, tunnel diode, BJT, JFET, MOS capacitor, MOSFET, LED, p-I-n and avalanche photodiode, integrated circuits fabrication process, oxidation, diffusion, ion implantation, photolithography, n-tub, p-tub and twin-tub CMOS process.
Straightforward problems are only asked, which can be solved with basic concepts in diode, BJT, JFET and MOSFET(less important). Expect theory questions also from other topics. 

(2) Signals and Systems:
Classification of signals and systems; System modeling in terms of differential and difference equations; Fourier series; Fourier transforms and their application to system analysis; Laplace transforms and their application to system analysis; Convolution and superposition integrals and their applications; Z-transforms and their applications to the analysis and characterization of discrete time systems; Random signals and probability; Correlation functions; Spectral density; Response of linear system to random inputs.
(3) Network Theory:
Network analysis techniques; Network theorems, transient response, steady state sinusoidal response; Network graphs and their applications in network analysis; Tellegen's theorem. Two port networks; Z, Y, h and transmission parameters. Combination of two ports, analysis of common two ports.
(4) Electromagnetic Theory:
Analysis of electrostatic and magneto-static fields; Laplace's and Poisson's equations; Boundary value problems and their solutions; Maxwell's equations; application to wave propagation in bounded and unbounded media; Transmission lines: basic theory, standing waves, matching applications, Elements of antenna theory and microwave basics.

Expect majority questions from this topic. Study this topic really well, as many theory questions and problems are asked from this. Many questions from microwave is asked which is out of syllabus for gate. Study satellite communication link design and antenna theory also. Questions from topics which we don’t usually find important for GATE can come.

(5) Analog Electronic Circuits:
Transistor biasing and stabilization. Small signal analysis. Power amplifiers. Frequency. response. Wide banding techniques. Feedback amplifiers. Tuned amplifiers. Oscillators, Rectifiers and power supplies. Op Amp, 555 timer, PLL, other applications. Pulse shaping circuits and waveform generators.

Mainly circuits with BJT and OPAMPS only asked. Also learn Rectifiers with zener diode
(6) Digital Electronic Circuits:
Boolean algebra, simplification of Boolean function Karnaugh map and applications; IC Logic gates and their characteristics; IC logic families: DTL, TTL, ECL, NMOS, PMOS and CMOS gates and their comparison; Combinational logic circuits; Half adder, Full adder; Digital comparator; Multiplexer De-multiplexer; ROM and their applications. Flip-flops. R-S, J-K, D and T flip-tops; Different types of counters and registers. Waveform generators. A/D and D/A converters.

Lot of very straight forward questions asked. So brush up everything and study A/D converters which is not that important for gate.
(7) Control Systems:
Transient and steady state response of control systems; Effect of feedback on stability and sensitivity; Root locus techniques; Frequency response analysis. Concepts of gain and phase margins; Constant-M and Constant-N Nichol's Chart; Approximation of transient response from Constant-N Nichol's Chart; Approximation of transient response from closed loop frequency response; Design of Control Systems; Compensators; Industrial controllers.

Very few questions are asked, that too straight forward negative feedback question, system response etc. and related to concepts in root locus and other graphical methods
(8) Communication Systems:
Random signals and noise: probability, random variables, probability density
function, autocorrelation, power spectral density. Analog communication systems: amplitude and angle modulation and demodulation systems, spectral analysis of these operations, superheterodyne receivers; signal-to-noise ratio (SNR) calculations for amplitude modulation (AM) and frequency modulation (FM) for low noise conditions. Digital communication systems: pulse code modulation (PCM), differential pulse code modulation (DPCM), digital modulation schemes: amplitude, phase and frequency shift keying schemes (ASK, PSK, FSK), matched filter receivers, bandwidth consideration and probability of error calculations for these schemes. Basics of TDMA, FDMA and CDMA and GSM.

Compared to gate syllabus, this is having lot of advanced topics. Study each and every heading in this. Anything can be asked (mostly direct but expect little tricky questions here). Even questions from coding theory have been asked even though not in GATE syllabus.
(9) Computer Engineering:
Number Systems. Data representation; Programming; Elements of a high level programming language PASCAL/C; Use of basic data structures; Fundamentals of computer architecture; Processor design; Control unit design; Memory organization, I/o System Organization. Microprocessors: Architecture and instruction set of Microprocessor's 8085 and 8086, Assembly language Programming. Microprocessor Based system design: typical examples. Personal computers and their typical uses.

This topic you will find difficult to study, as it is not for GATE and from previous year paper it is not easy for pin pointing even the correct syllabus. Many topics electronics students are not studying(mostly computer science people only knows the answers so get their help in finding answers in the previous year papers). Better don’t waste too much time in this. Study only basic concepts in computer networks, computer organization and microprocessor (study if you have done it as part of university syllabus and leave the more advanced topics in this and devote more time on to gate syllabus part)

What is Migration certificate? and steps to get Migration certificate

In this article, I am going to clear all your doubts about the migration certificate.

So many people are confused between a migration certificate and transfer certificate and some people’s heard this word for the first time when any board or institution asked migration certificate.

What is Migration certificate?

Migration certificate is one of the important certificates when you want to get admission in affiliated college/ institute in another board or another university. 

For example, if you are studying in X school which is affiliated to Y university/board, due to some reasons if you seek admission in another school Z which is affiliated to K university or board then you need a migration certificate because X and Z schools do not belong to same Board or university.
I hope you got an idea with that example.

How to get Migration Certificate?

You can apply through either online or offline mode to the respective board or university. Either a board or university has the right to issue this certificate only, No educational institutes will provide. You can collect the certificate directly from board/university or you can collect it from your institute after applying to board or university.

This certificate tells us that the board/university have no problem if you take admission in any other board or university.

How to Apply for migration certificate online?

Some boards provide online facility, but some boards or universities still in offline mode. You just check with the website of your respective board and confirm it yourself.

Difference between Transfer certificate(TC) and Migration certificate

Transfer certificate is another important certificate which is used to take admission in another affiliate institute in the same board or university but  this certificate can be issued by respective College/school/institute. But the migration certificate is used to take admission in any other board or university which is issued by Board or university only.

 Documents required to apply for migration certificate?

 Along with your application, you need to attach these documents to get document

  1. Provisional/ Degree certificate of the last course studied
  2. Current mark sheets
  3. Adhar card
  4. Fee Challan(fee depends on respective boards)
  5. Self-address envelopes with stamps

 Is that migration and character certificates are the same?

No, both are different Character certificate is used to tell your behaviour in the respective institute which is given by the respective school/college/institute
