Q1/ The bandwidth of an input signal to the PCM is restricted to 4KHZ. The input signal varies in amplitude from -3.8 V to + 3.8 V and has the average power of 30 mW. The required signal to noise ratio is given as 20 dB. The PCM modulator produces binary output. Assuming uniform quantization, Find the number of bits required per sample. i) ii) Outputs of 30 such PCM coders are time multiplexed. What would be the minimum required transmission bandwidth for this multiplexed signal?
