A modulating signal is a square wave as shown in the figure.

Sketch the amplitude modulated waveform.


#2

Given, the equation of carrier wave,
c® = 2sin(8$\pi$t)
(i) According to the figure,
Amplitude of modulating signal,
${ A }_{m }$ = 1V
Amplitude of carrier wave,

${ A }_{c }$ = 2

${ T }_{m }$ = 1s
