(a) A PCM communication system multiplexes two audio channels and one control channel. The channels have the following specifications: Audio channel: +3 V, 5 kHz, maximum quantization error of 0.4% of peak amplitude. Control channel: digital data of 150 kbps. Determine the followings: (1) Dynamic range (in dB) for each of the audio channel. [6 marks] (ii) Signal to quantization error (in dB) for each of the audio channel. [2 marks] (iii) Coding efficiency. [3 marks] (iv) Total output bit rate. [4 marks)
