What are the basic components of communication system? Which of the above components affect the signal most with noise, in a communication system?
The basic components of communication systems are
Fig. 15 Basic communication system
The signals are heavily affected by the noise in the transmission channel. In these region different types of noise such as additive whit Gaussian noise, flicker noise, thermal noise etc is added with the modulated signal.
How is a Phase Locked Loop (PLL) used for demodulation of FM signal? Mention the advantage of PLL demodulation.
