A 100 kHz band width is to accommodate 10 AM broadcasting stations simultaneously. What is the maximum modulating frequency permissible for each station?

Answer

5 kHz

Explanation

If `v kHz` is maximum modulating frequency permissible , then band width required for each station ` = 2 v`.
`:.` Number of stations ` = ("total band width" )/(2v)`
`10 = (100 kHz)/( 2 v)`
` v = (100)/( 10 xx 2 ) = 5 kHz`
