Assume that the transmitter circuitry limits the modulated output signal to a certain peak voltage value, say X volts. By employing this transmitter, show that the sideband power of a DSB-SC signal with a peak voltage of X is four times that of an AM (DSB-LC) signal having the same peak voltage and 100% modulation index, and is half that of a SSB-SC signal having the same peak voltage.
