An analog message signal has absolute bandwidth W. This message signal is sampled at a rate 30% more than the Nyquist rate, then each sample is quantized to one of 512 levels (note: 2° = 512). This results in a bit stream that is transmitted over a very long cable where the received power is 100 fW (femto = 10-15). To be received with acceptable bit error rate (BER), the received energy per bit must be E, > 10-19 J/bit. (a) Calculate the sampling rate used. State your answer in terms of W. (b) Calculate the bit rate of the transmitted signal. State your answer in terms of W. (c) Calculate the maximum data rate supportable over the cable. Give your answer in bps, kbps, Mbps or similar.
