A band width of 5 MHz is available for AM transmission. If the maximum audio signal frequency used for modulating the carrier is not to exceed 5 kHz, how many stations can be broad cast within this band simultaneously without interfering with eachother?

Text Solution

Verified by Experts

The correct Answer is:
500
Band width required for each station
`= 2 xx max`. freq. of audio signal
`= 2 xx 5 kHz = 10 kHz`
Max. number of stations , which can be broadcast within band width of `5 kHz`
