Problem#2: A compact disc (CD) records audio signals digitally by using PCM. Assume that the audio signal bandwidth equals 15 kHz. |(a) Ifthe Nyquist samples are uniformly quantized into L = 65, 536levels and then binary-coded, determine the number of binary digits required to encode a sample. (b) If the audio signal has average power of 0.1 watt and peak voltage of 1 volt. Find the resulting signal-to-quantization-noise ratio (SQNR) of the uniform quantizer output in part (a). |@ Determine the number of binary digits per second (hit/s) required to encode the audio signal (d) For practical reasons discussed in the text, signals are sampled at a rate well abovethe Nyquist rate. Practical CDs use 44,100 samples per second. If L = 65, 536, determine the number of bits per second required to encode the signal, and the minimum bandwidth required to transmit the encoded signal.
