1.	Which of the following stage is present in FM receiver but not in AM receiver?(a) Amplitude limiter(b) Demodulator(c) AM amplifier(d) MixerI got this question during an online interview.This intriguing question comes from Generation of DSBSC Waves in portion Double Sideband Suppressed Carrier Modulation of Analog Communications
Answer» CORRECT ANSWER is (a) Amplitude limiter Explanation: Amplitude Limiter circuit is used in FM receiver to remove the noise or any variation in amplitude PRESENT in the received signal. Thus, the output of the amplitude limiter has a constant amplitude. So it is only used in frequency MODULATION and not in amplitude modulation.
