Quantizing waveforms. Using Example 16.34 as a guide, compose a Matlab script to quantize the waveform

si = sin(2πi / 64) + sin(2πi / 48) V for 0 ≤i ≤512

a. What is the maximum amplitude of si ?

b. What is the number of bits that results in a quantization error magnitude |∊i |<0.01 V?

Example 16.34

Quantizing sinusoidal waveform

Figure 16.32 shows a Matlab script that illustrates quantization of a sinusoidal waveform. This script contains a while loop that insures the number of bits specified is 8 or less.
