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 LSB and USB are equal and given by
`= (mE_(c))/(2)= (0.5 xx 80)/(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= 1005 kHz`
