A binary PAM signal is generated by exciting a raised-cosine roll-off filter with a 50% roll-off factor and then DSB-SC amplitude modulating it on a sinusoidal carrier, as illustrated in Figure P-10.17. The bit rate is 2400 bps.
1. Determine the spectrum of the modulated binary PAM signal and sketch it.
2. Draw the block diagram illustrating the optimum demodulator/detector for the received signal, which is equal to the transmitted signal plus additive white Gaussian noise.
