1.	For getting 100% modulation, carrier amplitude should________(a) exceed signal amplitude(b) be equal to signal amplitude(c) be lesser than signal amplitude(d) be equal to 0This question was addressed to me by my college director while I was bunking the class.This intriguing question originated from Power Relations in AM Waves topic in section Amplitude Modulation of Analog Communications
Answer» Right CHOICE is (b) be equal to signal amplitude Easiest explanation: Modulation index is the amount of modulation present in a CARRIER WAVE. It is also DESCRIBED as the ration of the amplitude of message signal to that of carrier signal. Modulation Index (m) = VM/Vc, where Vm is maximum baseband or message signal amplitude and Vc is maximum carrier signal amplitude. So for m = 1, Vm should be equal to Vc.
