Question -
Answer -
It can be observed from the givenmodulating signal that theamplitude of the modulating signal, Am = 1 V
It is given that the carrier wave c (t) = 2 sin (8πt)
∴Amplitudeof the carrier wave, Ac = 2 V
Time period of themodulating signal Tm = 1 s
The angular frequency of the modulating signal is calculated as:
The angular frequency of thecarrier signal is calculated as:
From equations (i)and (ii), we get:
The amplitude modulated waveform of the modulating signal is shown in thefollowing figure.
(ii)Modulation index,
