(A) Given:Carrier frequency $f_{c} = 1.5\,MHz = 1500\,kHz$.Modulating signal frequency $f_{m} = 10\,kHz$.The lower side-band $(LSB)$ frequency is given by:$f_{LSB} = f_{c} - f_{m} = 1500\,kHz - 10\,kHz = 1490\,kHz$.The upper side-band $(USB)$ frequency is given by:$f_{USB} = f_{c} + f_{m} = 1500\,kHz + 10\,kHz = 1510\,kHz$.Thus,the lower and upper side-band frequencies are $1490\,kHz$ and $1510\,kHz$ respectively.

$A$ 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:
