Ok just some very simple Qs first
1. What exactly is the modulation index? Is it equal to Max amplitude of modulating signal / Max amplitude of carrier signal?
2. Do we have to normalize (Make the amplitude equal to 1) every modulating signal before we use it in our calculations? If so, how do we normalize signals with more than one component? Ex - 2Cos(2πf1*t) + 3Cos(2πf2*t)
3. After a modulating signal is normalized do we still say the modulation index = Max amplitude of modulating signal / Max amplitude of carrier signal (Using the original values of the amplitudes) when we are doing our calculations or just say it is equal to 1 / Max amplitude of carrier signal?
Thanks
