1% of `10^12` Hz of a satellite link was used for telephony . What is the number of channels (or subscribers ) , if the bandwidth of each channel is 8 KHz ?

A

A. `2.5xx10^8`

B

`B. 1.25xx10^6`

C

C. `2.5xx10^7`

D

D. `1.25xx10^7`

Text Solution

Verified by Experts

The correct Answer is:
B
Useful bandwidth =`1/100(10^12)=10^10`Hz
`therefore` No. of channels =`"Total useful bandwidth"/"Bandwidth per channel"`
`=10^10/(8xx10^3)=1.25xx10^6`
