What are different types of communication systems?

The four types of the communication system based on the signal specification are:Analog communication systems.Digital communication systems.Baseband communication systems.Carrier communication systems.

What are the main communication signals?

There are two basic types of signals, the analog signal and the binary digital signal. Therefore there are two types of communication systems: the analog and digital communication systems. The physical form of the information signal is audio, video and data.

What is the difference between FM and AM radio waves?

The difference is in how the carrier wave is modulated, or altered. With AM radio, the amplitude, or overall strength, of the signal is varied to incorporate the sound information. With FM, the frequency (the number of times each second that the current changes direction) of the carrier signal is varied.
