A bandwidth of 10 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 broadcasted within this band simultaneously without interfering with each other ?

Text Solution

Verified by Experts

The correct Answer is:

1000

Bandwidth required for each station `=2 xx` maximum frequency of audio single
`2 xx 5 = 10 k Hz`
Number of stations which can be broadcast within bandwidth of 10MHz
`= (10 xx 10 ^(6))/( 10 xx 10 ^(3)) = 1000`
