The modulation frequency of an AM radio ...

The modulation frequency of an AM radio station is 250 kHz, which is 10% of the carrier wave. If another AM station approaches you for license what broadcast frequency will you allot ?

Text Solution

Verified by Experts

According to question, modulation frequency 250 Hz is 10% of carrier wave
`f_("carrier")=250/0.1=2500kHZ`
`:.` Range of signal `2500+-250KHz=2250Hz` to 2750Hz
For 2000 kHz
`f_("mod")=200Hz`
`:.` Range `=1800KHz` to 2200 KHZ
