Best Programming Languages to get a job in top electronics core companies

No comments

Most of our ECE candidates has a dream to get a job in Top MNC companies like INTEL,CISCO, so on. Mostly these companies look for a candidates who has a strong domain level programming languages which are going to discuss on this post.So, one who has a strong dream to get a job in those companies must perfect in any one of these languages.

In today's world, an  Electronic student  may not be  a full-fledged software developer but one have to write codes every where anyway.  So students must be aware of some essential programming languages used in electronics field.

If one is looking for furthers studies or to work in core electronics company they must know the certain languages used in in this field.

Electronics based languages used in designing various circuits are

  • Embedded C
  • Matlab
  • VHDL
  • Verilog
  • Assembly level language
All these languages are used on various fields like chip designing, signals and systems, networking, telecommunications..etc.

One must start  learning C from the basics and must have complete grip on that language. It the most basic and essential language used in various fields. One can easily learn any other new language if he/she is perfect in C .  
Embedded C is only little different from C and It is used in Microprocessors and Micro-controllers, and it is used in ROBOTICS.

Learn  MATLAB if you are interested in  Signals and Systems, Communication Systems and other core telecommunication subjects.

VHDL and Verilog  are  a hardware description languages  used to model  analog and digital electronic systems.

Assembly language programming is another important language you should know being Electronics student.
These programming languages are used in the following fields:
  • Chip Design
  • Cutting edge device physics
  • Networking
  • Information Theory
  • Communication network
  • Manufacturing
  • Embedded systems
  • Signal/Image/Speech Processing

BARC previous questions sample paper for electronics(ECE)-2016

Barc is one of the Nuclear research centre in india, every year they recruit students based on their performance in GATE score or  OCES/DGFS written exam and interview, Here I am discussing about the Electronics written exam I already posted a GATE score required to get a call from BARC.

 From 2012 onwards they conducting written exam online, and the paper consists of 100 questions (technical). I already posted expected Syllabus and important topics to concentrate and prepare.

As the exam is  online, there is no question to get papers outside. But Here I am giving idea by posting sample Question paper for electronics based on the words of successful students, who has wrote the last year Barc exam.

In sample paper i am giving questions from some topics i didnt cover all the syllabus,and i will update more questions later on.. I will update some books names to prepare for barc exam on my later post, not only for barc they useful for all psu’s and competitive exams.
