Chapter 15 – Communication Systems
Communication systems deal with the transmission of information from one place to another using signals. This chapter explains the basic elements of a communication system, including the transmitter, communication channel, and receiver. Information is converted into electrical signals, transmitted through a medium like air, cables, or optical fibers, and then decoded at the receiving end. It also covers concepts such as modulation, which helps in efficient signal transmission over long distances, and different types of communication like analog and digital. Overall, the chapter provides a clear understanding of how modern communication technologies like radio, television, and mobile networks work. And it is important for Class 12 board exams and competitive exams like NEET and JEE.
