1.	Which of the following receiver does not have an amplitude limiter stage?(a) AM(b) PM(c) FM(d) Both AM and FMThe question was posed to me in an online quiz.This interesting question is from Noise in Phase Modulation in division Noise of Analog Communications
Answer» CORRECT answer is (a) AM The 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.
