The message signal is usually of:

A: If the amplitude of a message signal is half of the amplitude of the carrier wave, then the index of modulation is 50%. R: In amplitude modulation the amplitude of the carrier wave varies in accordance with the signal voltage of the message signal.

Given three reasons why modulation of a message signal is necessary for long distance transmission.

The disturbance or distortion in the transmission and processing of message signals is called

The disturbance or distortion in the transmission and processing of message signals is called

(A): A FM signal is less susceptible to noise than an AM signal. (B) : In FM transmission, the message signal is in the form of frequency variations of carrier waves. During modulation process, the noise gets amplitude modulated.

In communication system message signal is modulated with carrier signal given below V_in = 20 sin[2 pi (1500t)] V_c = 80 sin[2pi (100000t)] Find percentage modulation
