All About Communication Systems……

Dear  Students,

It gives me pleasure to note that the series ‘ALL ABOUT…..’ clubbing the posts for every single Unit started a few days back with All About Electrostatics….as the first post was well received & appreciated.

Taking impetus from the response,a number of other units have also been clubbed.

The present ‘ALL ABOUT…..’ series by the author in ‘physicsbeckons’  is in line with our aim  to help you learn ‘Physics without fear’.

Here is ALL ABOUT Communication Systems for you…..

This unit in the CBSE class 12 syllabus carries about 5 marks and has a special advantage that generally direct questions are asked in this unit. The numerical problems in this unit are also very simple.
