+1.2 V. This signal is sampled, uniformly quantized, and transmitted via binary polar baseband
modulation. The sampling rate is 25% above the Nyquist rate.
(a) If the required SNR for video quality is at least 53 dB. determine the minimum binary pulse
rate (in bits per second) for this baseband transmission.
(b) Find the minimum bandwidth required to transmit this signal without ISI when a
raised-cosine pulse shape with roll-off factor r=0.3 is used.
