An audio signal consists of two distinct sound. One a human speech signal in the frequency band of `200Hz` to `2700Hz`, while the other is a high frequency music signal in the frequency band of `10200Hz` to `15200Hz`. The ratio of the AM signal together to the AM signal band width required to send just the human speech is:

A

`6`

B

`5`

C

`3`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
A
Band width for both signals
`15200Hz-200Hz=15000Hz`
Band with for human speech
`2700-Hz-200Hz=2500Hz`
The ratio `=15000/2500=6`
