Question

What is the role of amplitude limiter in fm receiver?

Answer 1

Answer:

Amplitude limiter in FM receivers are used to remove the amplitude variations. ... In FM signal the frequency of the carrier is varied. So if there are any variations in the amplitude of the received wave, it is due to noise or interference in the communication channel.

Answer 2

The role of amplitude limiter in FM receiver is to remove amplitude variations.

• An amplitude limiter is a device that is used to keep the amplitude of the signal in the FM receiver at a constant value.
• The limiter is a kind of clipping device. It is a circuit for which the output tends to remain constant even if there are variations in the input signal being provided.
• The frequency of the carrier is generally varied in the case of FM signals, due to interference or noise in the channel. Limiter removes these variations and helps in keeping the signal amplitude at a constant value.
