Q2): consider a 3 kHz band limited voice signal sampled at 8000 sample/sec to be transmitted over a channel. The input variés from -3.8v to +3.8v and has average power of 30 mW. The required signal to quantization ratio is 20 dB. a. Determine the PCM data rate if a 32 synchronization bits are inserted every 224 data bits. b. Determine the minimum required transmission bandwidth if 20 PCM coders are time multiplexcà . c. Determine the RMS value of quantization noise.
