Abstract

This is a block quantizer which converts a given block of samples into an optimum sequence of numbers describing the sampled signal with minimum distortion due to the quantizing process. The quantizer self-adjusts the basic parameters, i.e., quantizing step Q, d.c. level C and the sequence of numbers fn, describing the signal for each block of samples for a minimal Mean Squared Error.
