Vedclass · Answer

(B) In communication systems,amplitude modulation $(AM)$ typically operates in the medium wave $(MW)$ and short wave $(SW)$ bands,which range from approximately $540 \ kHz$ to $30 \ MHz$. Frequency modulation $(FM)$,on the other hand,operates in the very high frequency $(VHF)$ band,typically ranging from $88 \ MHz$ to $108 \ MHz$. Since the carrier frequency used in $FM$ $(f_f)$ is significantly higher than the carrier frequency used in $AM$ $(f_a)$,we conclude that $f_a < f_f$.

If $f_a$ and $f_f$ represent the carrier wave frequencies for amplitude and frequency modulations respectively,then
