A sinusoidal carrier wave of amplitude 4...

A sinusoidal carrier wave of amplitude 40 V is amplitude modulated by a sinusoidal signal voltage. What is the amplitude of each side band if the modulation index is 25%.

A

A. 5 V

B

B. 4 V

C

C. 6 V

D

D. 8 V

Text Solution

Verified by Experts

The correct Answer is:
A
`A_C` = 40 V and `mu`=25% = 0.25
`therefore` Amplitude of each side band `=(muA_C)/2=(0.25xx40)/2`=5 V
