A message signal m(t) with BW 5kHz,∣m(t)∣<=1 V and power 0.1 W is transmitted using FM over a channel of bandwidth 100kHz and attenuation of 160 dB. The noise is white with PSD 5×10 −21 W/Hz and the transmitter transmits the signal with 10 kW of power. a) Consider a frequency sensitivity kf of 25kHz/V. What is the SNR at the output of the receiver?
