Question

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

• A. A and R are true and R is the correct explanation of A
• B. A and R are true but R is not correct explanation of A
• C. A is true but R is false
• D. A is false but R is true.

Answer 1

The correct option is A A and R are true and R is the correct explanation of A

Basically in amplitude modulation the amplitude of noise is modulated during the process of modulation. thus the amplitude of noise is also increased which creates problem.
