Consider the front end of the receiver that is shown in the block diagram in Figure P-14.19. The received signal power at the input to the first amplifier is -113 dBm, and the received noise power spectral density is -175 dBm/Hz. The bandpass filter has a bandwidth of 10 MHz, and gains and noise figures are as shown. Determine the signal-to-noise ratio Ps/Pn at the input to the demodulator.
