Amplitude limiter in FM receivers
Amplitude limiter in FM receivers are used to
a) Remove amplitude variations due to noise
Correct Answer: a.) Remove amplitude variations due to noise
Amplitude limiter in FM receivers are used to remove the amplitude variations. The limiter does this by clipping the received modulated wave. 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. So these amplitude variations are remover by the amplitude limiters.
