1.	Amplitude modulation has ______ relationship between the quality of the received signal and the power of the received signal.(a) No(b) Non linear(c) Constant(d) LinearThe question was asked in an interview for internship.My question is from Frequency Modulation Vs. Amplitude Modulation topic in division Modulation Techniques for Mobile Radio of Wireless/Mobile
Answer» The correct CHOICE is (d) Linear To elaborate: In amplitude modulation SCHEMES, there is a linear relationship between the quality of the received SIGNAL and the power of the received signal. AM signals superimpose the exact relative AMPLITUDES of the modulating signal onto the carrier.
