Vedclass · Answer

(B) The bandwidth required for a single amplitude modulated $(AM)$ station is twice the highest modulating frequency $(f_m)$.Given,$f_m = 15\, kHz$.Therefore,the bandwidth per channel = $2 	imes f_m = 2 	imes 15\, kHz = 30\, kHz$.The total available bandwidth is $300\, kHz$.The number of stations that can be accommodated = $\frac{	ext{Total Bandwidth}}{	ext{Bandwidth per channel}} = \frac{300\, kHz}{30\, kHz} = 10$.

The number of amplitude modulated broadcast stations that can be accommodated in a $300\, kHz$ bandwidth for the highest modulating frequency of $15\, kHz$ is:
