Consider that you desire a digital transmission system, such that the quantization distortion of any audio source does not exceed ±2% of the peak-to-peak analog signal voltage. a. If the audio signal bandwidth and the allowable transmission bandwidth are each 4000Hz. And the sampling takes place at Nyquist rate, what value of bandwidth efficiency (bits/s/Hz) is required. b. Repeat part (a) except that the audio signal bandwidth is 20kHz (high fidelity), yet the available transmission bandwidth is still 4000Hz.
