Q6) 24 speech signals having a bandwidth of 3.5 Khz are each sampled at a rate of 5 Khz and PCM encoded using a 256 level uniform quantizer. All the 24 signals are TDM multiplexed together before transmission. What is the null to null transmission bandwidth BT required by the joint TDM signal if NRZ rectangular pulses are used? What is the SNR of the speech signals in decibels due to the quantization noise?
