Pulse Code Modulation (PCM) - NETWORK ENCYCLOPEDIA

Problem 2:In a PCM system, the bit error rate due to channel noise is 10^-3. Assume that the peak signal-to-noise ratio on therecovered analog signal needs to be at least 20dB.(a) Find the minimum number of quantizing steps (M) that can be used to encode the analog signal into aPCM signalIf the original analog signal had an absolute bandwidth of 3kHz,(b) what is the null band-width of the PCM signal for the polar NRZ signaling?(c) What is the null band-width of the PCM signal for Unipolar RZ sig
