Step 1
The modulation index is defined as the ratio of the amplitude of the modulating signal to the amplitude of the carrier signal. Mathematically, Modulation index = (Amplitude of modulating signal) / (Amplitude of carrier signal) Here, the modulation index is given Show more…

A modulating signal 9 sin(2π*10^2t) is used to modulate a carrier signal 12 sin (2π*10^3t). Find the modulation index, frequencies of wideband components, and their amplitudes, bandwidth of the modulated signal. Also, draw the frequency spectrum of the AM wave.
