Digital Signal Modulations

No comments
In general modulation is defined as a process of varying one or more properties of a signal that carries information. We basically have two types of signals,ie analog signals and digital signals.
Analog Signals are continuous time varying signals where as digital signals are discrete time signals.
fig: Analog and digital signals
In olden days Analog signals were used in for transmitting information from one place to another.But it has many disadvantages like information loss and high noise while transmitting, even after demodulation the complete transmitted information could not be retrieved. So there has been a shit from analog to digital signals. with digital signals there are many advantages and because of this we see all our electronic devices relay only on digital signals and not on analog.

The digital signals are transmitted using various modulation techniques according to the requirements.In modulation the major components are Signal that carries information, modulator,transmitting medium  and demodulator.

Common modulation methods are:
  • Amplitude modulation (AM), in which the height (i.e., the strength or intensity) of the signal carrier is varied to represent the data being added to the signal.
  • Frequency modulation (FM), in which the frequency of the carrier waveform is varied to reflect the frequency of the data.
  • Phase modulation (PM), in which the frequency of the carrier waveform is varied to reflect changes in the frequency of the data (similar but not the same as FM).
  • Polarization modulation, in which the angle of rotation of an optical carrier signal is varied to reflect transmitted data.
  • Pulse-code modulation in which an analog signal is sampled to derive a data stream that is used to modulate a digital carrier signal.
The main aim of modulation today is to squeeze as much data into the least amount of spectrum possible. That objective, known as spectral efficiency, measures how quickly data can be transmitted in an assigned bandwidth. The unit of measurement is bits per second per Hz (b/s/Hz). Multiple techniques have emerged to achieve and improve spectral efficiency.

Do you know how X-rays are made?

No comments
We come across X-rays mostly in medical field,whenever our bones get damaged X-rays are taken so that we can come to know were exactly the bone has been fractured.In general X-rays used to scan the inner part of things which are invisible to our naked eyes.
   X rays are electromagnetic rays whose wave length ranges from  0.01 to 10 nanometers. 


They are produced when electrons strike a metal target. The electrons are liberated from the heated
 filament and accelerated by a high voltage towards the metal target. The X-rays are produced when the electrons collide with the atoms and nuclei of the metal target.

Due to their ability to penetrate certain materials, X-rays are used for a number of nondestructive evaluation and testing (NDE/NDT) applications, particularly for identifying flaws or cracks in structural components

How Antenna can be made ?

No comments
In our daily life we come across Antennas used for be various devices.
What is the nature of Antenna?
If a parallel wire transmission line is left open, the electric and magnetic field escape from the line and radiate into the free space. This radiation however is insufficient and unsuitable for reliable for transmission and reception.

Know about MATLAB

No comments
Every ECE Student will come across this subject in his/her academics,but do you know the significance of this subject? If you don't know, go through these lines below.....

The name MATLAB stands for matrix laboratory. MATLAB was originally written to provide easy access to matrix software developed by the LINPACK and EISPACK projects, which together represent the state-of-the-art in software for matrix computation.

MATLAB is a high-performance language for technical computing. It integrates computation, visualization, and programming in an easy-to-use environment where problems and solutions are expressed in familiar mathematical notation.

Typical uses include:
  * Math and computation
  * Algorithm development
  * Modeling, simulation, and prototyping
  * Data analysis, exploration, and visualization
  * Scientific and engineering graphics



MATLAB is an interactive system whose basic data element is an array that does not require dimensioning. This allows you to solve many technical computing problems, especially those with matrix and vector formulations, in a fraction of the time it would take to write a program in a scalar noninteractive language such as C or Fortran.


MATLAB has evolved over a period of years with input from many users. In university environments, it is the standard instructional tool for introductory and advanced courses in mathematics, engineering, and science. In industry, MATLAB is the tool of choice for high-productivity research, development, and analysis.

MATLAB features a family of application-specific solutions called toolboxes. Very important to most users of MATLAB, toolboxes allow you to learn and apply specialized technology. Toolboxes are comprehensive collections of MATLAB functions (M-files) that extend the MATLAB environment to solve particular classes of problems. Areas in which toolboxes are available include signal processing, control systems, neural networks, fuzzy logic, wavelets, simulation, and many others.
