A telephonic communication service is working at carrier frequency of 10 GHz. Only 10% of it is utilized for transmission. How many telephonic channels can be transmitted simultaneously if each requires a bandwidth of 5 kHz?

A

`2xx 10^(5)`

B

`2 xx 10^(6)`

C

`2 xx 10^(3)`

D

`2 xx 10^(4)`

Text Solution

Verified by Experts

Frequency of carrier waves
= ` 10 xx 10^(9)`Hz
The bandwidth that can be utilized
= ` 10 xx 10^(9) xx (10)/(100) Hz = 10^(9) Hz`
`therefore` Number of channels that can be transmitted
`= (10^(9))/(5 xx 10^(3)) = 2 xx 10^(5)`
`therefore` The option A is correct.
