Question:
In this problem, we use computer simulation to compare the performance of a companded PCM system using the law against that of the corresponding system using a uniform quantizer. The simulation is to be performed for a sinusoidal input signal of varying amplitude.
(a) Using the μ-law described in Table, plot the output signal-to-noise ratio as a function of the input signal-to-noise ratio, both ratios being expressed in decibels.
(b) Compare the results of your computation in part (a) with a uniform quantizer having 2.56 representation levels.
