A PCM system with uniform quantization is used to transmit a speech signal. The bandwidth of the signal is equal to 6 KHz. At the receiver we require an SNR in the reconstructed signal equal to 40 dB.
a) What is the minimum sampling rate for the speech signal?
b) In the signal quantization what is the smallest number of possible levels?
c) What is the bit rate of the PCM signal, using the number of quantization levels in b) and the sampling rate in a)?
d) Explain the reason for using non-uniform quantizers.
