Assignment:
[Quantization Noise in DM] Load the sampled speech signal given in Illustrative Problem. Expand the length of the sequence to 64000 by linearly interpolating and inserting three additional samples between successive samples of the original 16,000-point sequence. Apply DM to the interpolated sequence using ? = 0.034 and evaluate the SQNR and plot the quantization error. Compare the SQNR with that of DPCM that employs 4 bits/sample on the original 16,000-point sequence.
Provide complete and step by step solution for the question and show calculations and use formulas.
