signal of bandwidth 4 kHz is samples at Nyquist rate and transmitted using PCM with uniform quantization. If the number of quantization levels L is increased from 64 to 256. Find the following: The number of bits sample in the old and new PCM systems. The change in SNR measured in dB. (improved or decreased, and by how many times). The transmission bandwidth before and after increasing the quantization levels. Find the percentage of change in the bandwidth.
