A sinusoidal carrier voltage of `80 "volts"` amplitude and `1MHz` frequency is amplitude modulated by a sinusoidal voltage of frequency `5 kHz` producing `50%` modulation. Calculate the amplitude and frequency of lower and upper side bands.

Explanation

Amplitude of both `LSB` and `USB` are equal and given by
`=(mE_(c))/(2)=(0.5xx80)/(2)=20"volts"`
Now frequency of `LSB=f_(c)-f_(s)`
`=(1000-5)kHz=995kHz`
Frequency of `USB=f_(c)+f_(s)`
`=(1000+5)kHz=1005kHz`
