Question

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?

Professor PC Thomas Classes · Answer

Carrier frequency $f_c = 250/0.10 = 2500$ kHz. Bandwidth required = $2 	imes 250 = 500$ kHz. Next channel at $2500 - 500 = 2000$ kHz.
