Any expect can guide /explain how to draw the (ii). Part (i), I have solved. Only need part (ii). attached is the picture.
Same signal is applied to both inputs of a product modulator so that the inputs are:
V1 = V2 = Vin
Product modulator characteristic is:
Vout = 0.1V1V2
Input waveform is described by:
Vin = 12coswt-3cos3wt
(i) Deduce an expression for the output waveform in terms of its frequency components.
(ii) Draw the line amplitude spectrum of the output waveform.
