Vedclass · Answer

(B) In amplitude modulation,the resultant signal consists of the carrier frequency $(f_c)$ and two sideband frequencies: the Upper Sideband $(f_c + f_m)$ and the Lower Sideband $(f_c - f_m)$.Given:Carrier frequency $f_c = 2\ MHz = 2000\ kHz$.Modulating signal frequency $f_m = 5\ kHz$.The frequencies present in the modulated wave are:$1$. Carrier frequency = $2000\ kHz$.$2$. Upper Sideband $(USB)$ = $f_c + f_m = 2000\ kHz + 5\ kHz = 2005\ kHz$.$3$. Lower Sideband $(LSB)$ = $f_c - f_m = 2000\ kHz - 5\ kHz = 1995\ kHz$.Thus,the frequencies are $2005\ kHz$,$2000\ kHz$,and $1995\ kHz$.

$A$ signal of $5\ kHz$ frequency is amplitude modulated on a carrier wave of frequency $2\ MHz$. The frequencies of the resultant signal is/are
