Question 4: (15 points) Consider an audio signal with spectral components in the range from 40 Hz to 5,000 Hz. Assume that a sampling rate of 12kHz will be used to generate a PCM signal. The audio signal has an average power of 0.5W and peak voltage of 4V.C (a) For SNR=25db, what is the number of (uniform) quantization levels needed? How many bits are required to encode the PCM data? (b) What data rate is required? (c) What is the minimum bandwidth required to transmit the encoded signal.
