Dear Students,

The subjects you cover during the current semester will help understand HOW an electronic system can take an input and provide an out.

Input is usually information which is taking the shape of an electrical signal (voltage or current). Output will also naturally be an electrical signal.

What we all must understand is that signal and information are the same. It is just that the information which is in a non-electrical domain (like a voice saying "Hello" or a photograph showing your merit certificate) has to be first converted into the electrical domain. Only then can it be processed before generating the output.


What is signal processing ?

Processing can be simply termed as ANY MATHEMATICAL OPERATION on the signal.

By mathematical operation we mean increasing/decreasing (multiplication with a scalar), addition, subtraction, multiplication, division, integration, differentiation, logarithmic or antilogarithmic transformation etectera are all part of signal processing.

So , in electronic communications we mainly deal with WHEN, WHY and HOW to perform these operations.

While modern computers and simulation software provide easy means of testing the signal processing systems without designing them practically, electronic devices such as transistors, FETs, integrated circuits, microprocessors, microcomputers, FPGAs etc provide the hardware base to realise the actual system as a usable PRODUCT.

Keep refining your grip on math skills, basic electronics and using computer based software for simulation.

The more time you spend on these, the more meaningful your text books, classwork and lab activities will be.

Feel free to ask ANY doubts anytime.
