An analog signal is sampled, quantized and encoded into a binary PCM wave. The number of representation levels used is L=32768. A synchronizing bit is added at the end of each codeword representing a sample of the analog signal. The resulting PCM wave is transmitted over a channel of bandwidth BT=28 (kHz), using a binary PAM system with raised-cosine spectrum, where the roll-off factor is a=0.75. Then, the information is transmitted at the rate Rb=____ (bps) through the channel. The analog signal is sampled at the rate fs= (Hz). The maximum possible value for the highest frequency component of the analog signal is fH= (Hz).
A、Rb=32k, fs=2k, fH=1k
B、Rb=32k, fs=4k, fH=2k
C、Rb=48k, fs=2k, fH=1k
D、Rb=48k, fs=4k, fH=2k
