The message signal

(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 amplitude modulation, the message signal V_(m)(t)=10sin(2pixx10^(5)t) volts and Carrier signal V_(C )(t)=20sin(2pixx10^(7)t) volts The modulated signal now contains the message signal with lower side band and upper side band frequency, therefore the bandwidth of modulated signal is alpha KHz. The value of alpha is

For an amplitude modulated wave message signal peak voltage = 20V carrier signal peak voltage = 20V. What is modulated index.

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

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

A message signal is used to modulate a carrier frequency. If the peak voltages of message signal and carrier signals are increased by 0.1% and 0.3% respectively, then

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