| Abstract: | In digital communication and data compressing technology, quantizer is an important part. Based on the relationship between equal probability quantizing and mean square error quantizing, the paper gives a simple and direct algorithm for designing MSE quantizer of signals whose probability density functions are Gaussian distribution or exponential function such as Laplacian distribution. |
