(A) Given:Carrier frequency,$f_c = 1.5 \, MHz = 1500 \, kHz$Modulating frequency,$f_m = 10 \, kHz$The side-band frequencies in amplitude modulation are given by $(f_c - f_m)$ and $(f_c + f_m)$.Lower side-band frequency $(LSB)$ $= f_c - f_m = 1500 \, kHz - 10 \, kHz = 1490 \, kHz$Upper side-band frequency $(USB)$ $= f_c + f_m = 1500 \, kHz + 10 \, kHz = 1510 \, kHz$Thus,the side-band frequencies are $1490 \, kHz$ and $1510 \, kHz$.

$A$ sinusoidal carrier voltage of frequency $1.5 \, MHz$ and amplitude $50 \, V$ is amplitude modulated by a sinusoidal voltage of frequency $10 \, kHz$ producing $50 \% $ modulation. The lower and upper side-band frequencies in $kHz$ are:
