Quantization Error in Uniform PCM

The objective of this problem is to evaluate the quantization error in quantizing a Gaussian source using uniform PCM.

1. Generate 500 zero-mean, unit-variance Gaussian random variables and quantiz( them by using a uniform 64-level PCM quantizer and encoder. Plot the 500-poin sequence generated.

2. Determine the SQNR for the 64-level quantizer.

3. Determine the first five values of the sequence, the corresponding quantized values, and the corresponding PCM code words.

4. Plot the quantization error, defined as the difference between the input value am the quantized value, for the 500-point sequence.
