1.	Which of the following statement about Amplitude Limiter is not true?(a) The circuit is always biased in class C amplifier(b) When the input increases and becomes greater than the threshold of limiting, the gain starts decreasing(c) The output must be tuned(d) Leak-type bias must be usedThe question was posed to me during an online interview.This intriguing question comes from Noise for SSB-SC topic in portion Noise of Analog Communications
Answer» Correct CHOICE is (a) The circuit is always biased in class C amplifier The explanation is: Amplitude Limiter REMOVES the amplitude of output SIGNALS to the desired margin irrespective of VARIATIONS in the INPUT signal. It is always biased in class C amplifier by virtue of the leak-type bias. Amplitude limiter is present in FM receiver and not AM receiver.
