The average noise power per unit bandwidth measured at the front end of an AM receiver is .0001 watt per Hertz. The modulating wave is sinusoidal, with a carrier power of 10 kilowatts, and a sideband power of 5 killowatts per sideband. The message bandwidth is 5 kHz. Assuming the use of an envelope detector in the receiver, determine the output signal-to-noise ratio of the system (write in dB value please).
