i just had my first Signals processing Lecture, during AM modulation part my prof said that:
V_AM(t) = (V_main(t) + 1) * V_Carrier
while V_Carrier = sin (omega * t)
1-is there a proof that we get the envelop of a function by adding one then multiplying by some trig value?
2- what's the difference between main message function m(t) = A Cos(omega *t) and the term V(t) = A Sin(omega *t) ?
