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

Explanation

Amplitude of both LBS and USB are equal and given by
`(mEc)/(2)=(0.5xx80)/(2)=20`volts
Now frequency of LSB =`f_(C)-f_(s)=(1000-5)kHz` Frequency of USB =`f_(C)-f_(s)`=(1000-5)kHz
