### Compute the total signal power from the specturm

Assignment Help Electrical Engineering
##### Reference no: EM13247521

A communication system must transmit the following real valued signal:

v(t) = 4cos(2pi*10MHz*t) + 2cos(2pi*20MHz*t)+cos(2pi*30MHz*t)V

For this signal, sketch the positive-frequency power specturm P(f>0) clearly identify power levels at each frequency, then compute the total signal power from your specturm.
