Description: For a file(.wave)
• Find the sampling frequency and the number of bits per sample.
• Re-quantize the samples using the following methods:
o Linear Quantization
o A-Law Companding with A=87.6
o μ-Law Companding with μ=255
• Use a mid-rise quantizer with 4, 5, 6, 7, and 8 bits per sample.
• Obtain the signal-to-quantization noise ratio (SQNR) for each of the
above 15 cases.
• It is required to plot the SQNR (dB) versus the number of bits per
sample for linear quantization, A-law companding, and μ-law
companding. All 3 plots may be on the same figure, if convenient.
