A telephone link operating at a center frequency of `10 GHz` is etablished. If `1%` of this is a available then how many telephone channel can be simultaneously given when each telephone covering a band width of `5kHz`?

A

`2xx10^(4)`

B

`2xx10^(6)`

C

`2xx10^(4)`

D

`2xx10^(6)`

Text Solution

Verified by Experts

The correct Answer is:
a
`1%` of `10GHz=10xx10^(9)xx(1)/(100)=10^(8)Hz`
Number of channels `=(10^(8))/(5xx10^(3))=2xx10^(4)`
