Class 12 Physics Chapter 15 Communication Systems
We all know that the three basic elements of communication include the transmitter, channel, and the receiver. This chapter explains the role of each element in details. It also talks about the bandwidth of signals, the bandwidth of transmission medium, the necessity of modulation, amplitude modulation, production and detection of amplitude modulated wave, propagation of electromagnetic waves, etc. After a thorough explanation of the topics, there are exercises to solve at the end of the chapter.
As we all know, 12th is the most important class for all the students, as after this they move to their college level. But you can get admission in a good recognized institute or university, only when you have scored the minimum qualifying marks. And it is only then, you will be able to get good jobs or get placed directly from campus recruitment, conducted by colleges. Therefore, it very necessary for you to build a strong base in Class 12 Physics subject and understand the concepts deeply.
