An AM receiver, operating with a sinusoidal modulating signal and 80 percent modulation, has an output signal-to-noise ratio of 30 dB.

a) What is the correspoding carrier- to - noise ratio?

b) By how many decibels can we decrease the carrier- to- noise ratio so that the system is operating just above the threshold?
