1.	What happens when the amplitude of the modulating signal is greater than the amplitude of the carrier?(a) Decay(b) Distortion(c) Amplification(d) AttenuationThis question was addressed to me by my school teacher while I was bunking the class.I would like to ask this question from Amplitude Modulation and Modulation Index in division Amplitude & Frequency Modulation of Avionics
Answer» Correct OPTION is (b) Distortion The explanation is: The zero reference line of the modulating signal coincides with the peak value of the unmodulated carrier. Because of this, the RELATIVE amplitudes of the carrier and modulating signal are important. When the AMPLITUDE of the modulating signal is GREATER than the amplitude of the carrier, distortion will OCCUR.
