Unformatted text preview: bandwidth required for no ISI and a rolloff factor of r = 1? b. Repeat part a if binary PCM is used and the samples are quantized to eight levels. c. Repeat part b for 128 quantization levels. 3. What is the theoretical minimum bandwidth required to transmit a 10Kbps binary PCM waveform? How large can the rolloff factor, r, be if the allowable bandwidth is 6 KHz? 4. The binary sequence: 1 0 0 1 0 1 1 0 0 1 0 is input to a duobinary modulator with precoding. Complete the table shown below. Data sequence, x k 1 0 0 1 0 1 1 0 0 1 0 Precoded seq. w k Trans. bipolar seq, w k Received seq, y k Decoded output...
