Practice 2: Quantization Error and Companding Objective: To study the performance of uniform quantization and the benefits of using non-uniform quantization using companding. The signal s(t)=10exp(t)+sin(2t) is sampled at an 20Hz rate over the interval from 020 seconds. The signal then quantized. Consider the following code a guide for you Use the provided code as a guide in answering the following questions, Q.2.1 If 8-bit equalization is performed without companding, use the provided code to generate the graphs of original, quantized, and error signals. Determine the root-mean-square (rms) error between the unquantized and quantized signals. Q. 2.2 If 8-bit quantization is performed with a -law compander with =100, se the provided code to general the graphs of signal, quantized signal, and error signals. Determine the rms error between the unquantized and quantized signals ] Exercise 2: Use the above codes to study the effect of the number of bits on the rms quantization error (in dB ), with and without companding.
