Draw a block diagram of a simple modulator for obtaining amplitude modulated signal. A carrier wave of peak voltage 12 V is used to transmit a message signal. What should be the peak voltage of the modulating signal in order to have a modulation index of 75%?

Question

Philoid · Accepted Answer

The block diagram of a simple modulator is as follows:

Given, peak carrier voltage,

Modulation index,

Let the peak voltage of modulating signal be

We know,

Hence, peak voltage of modulating signal should be 9V.
