Abstract
The optimum (minimum mean-squared-error) and optimum uniform quantizing characteristics for Laplacian- and gamma-distributed signals are given in tabular form. The performance of these quantizers in real speech pulse-code modulation (PCM) and differential pulse-code modulation (DPCM) systems is investigated and compared with that obtained when the μ-law quantizing characteristic is used.
