An am transmitter has a carrier power of 50 w at a carrier, Ask an Expert

Engineering

An AM transmitter has a carrier power of 50 W at a carrier frequency of 12 MHz. It is modulated at 80% by a 1-kHz sine wave.

(a) How much power is contained in the sidebands?

(b) Suppose the transmitter in part (a) can also be used to transmit a USB signal with an average power level of 50 watts. By how much (in dB) will the signal-to-noise ratio be improved when the transmitter is used in this way, compared with the situation in part (a)?
