A 1000 kHz carrier wave is modulated by ...

A 1000 kHz carrier wave is modulated by an audio signal of frequency range 100-5000 Hz. Then, the width of channel (in kHz) is

A

10 KHz

B

20 KHz

C

30 KHz

D

40 KHz

Text Solution

Verified by Experts

The correct Answer is:
A
Band width or (width of the channel )
= 2 x (maximum frequency of the modulating signal or audio frequency signal)
= 2 x 5000 Hz = 10,000 Hz = 10 KHz
