EE 552 -Communication Theory-Spring 2010 Homework #2 - Optimal Scalar Quantization Techniques Date Assigned: Thursday, February 18 Date Due: Thursday, February 25 1) Use the Lloyd-Max algorithm to find the optimum 5 level quantizer for the pdf: ( 29 p x e x = - 1 2 Compute the resulting average SNR. Hints: * The symmetry of this distribution should save you 3/5 of your effort. * It will simplify your effort greatly to make use of a numerical integration routine such as the ‘int’ function in Matlab
