FM and PM are two ways of angle modulation.(a) True(b) FalseThis quest

1.	FM and PM are two ways of angle modulation.(a) True(b) FalseThis question was addressed to me in semester exam.My question comes from Frequency Discrimination Method topic in division SSB Modulation of Analog Communications
Answer» Correct choice is (a) True Easiest explanation: In angle modulation, PHASE or frequency of the carrier wave is varied with respect to the instantaneous AMPLITUDE of the message SIGNAL. The general expression for FM and PM are as follows: FM (t) = Ac sin (2πfct + βsin(2πfmt)), PM (t) = Ac sin (2πfct + βcos(2πfmt)), where symbols have their usual meaning.
