ABSTRACT:
This data compression system further reduces previously-formed digital words representing samples of non-uniformly quantized and encoded analog speech, by normalizing and reencoding the original input digital word samples into smaller words using block coding wherein the input words are bit-reduced by normalizing a block of samples to the maximum amplitude sample value. Features of the invention include concatenating the most significant bit of the maximum value block code (first digital word) with the least significant bit of the segment bits part of the normalized input digital word (third digital word).
