Question

3323 Modern Digital and Analog Communication Question A compact disc (CD) records audio signals digitally by using PCM. Assume that the audio signal bandwidth equals 15 kHz (a) If signal is sampled at the Nyquist rate and the samples are uniformly digitized into L 65,536 levels and then binary-coded, determine the number of bits required to encode a sample (b) If the audio signal has average power of 0.1 W and a maximum peak voltage of 1 V. Find the resulting ratio of signal to quantization noise (SQNR) of the uniform quantizer in part (a) (c) Determine the Bit Rate required to encode the audio signal (d) In practice audio signals to be recorded on CD are sampled at 44,100 samples per second. If L 65,536, determine the Bit Rate
