A 500 KHz carrier wave is amplitude modulated by an audio signal of frequency span of 200 Hz to 4000 Hz. What is the bandwidth of the channel?

A

a. 4 KHz

B

b. 6 KHz

C

c. 8 KHz

D

d.10 KHz

Text Solution

Verified by Experts

The correct Answer is:
C
The bandwidth of the channel = 2 x highest modulating frequency
= 2 x 4000 Hz = 8000 Hz = 8 KHz
