COMPRESSION OF DIGITAL MEASUREMENT SIGNALS BY IMPROVED REVERSE SCALING RECONSTRUCTION METHOD

Jerzy Jurkiewicz, Waclaw Gawedzki

Abstract

It is noticed in the paper that scaling of digital measurement signals and their registration in format which is comfortable to investigations during computer processing increase their volume. Possibility of realization a reverse scaling operation as an initial processing method preceding compression is mentioned. <br /> The authors proposed to complete initial processing by generally well-known operation - calculation of differences between succeeding samples and they tested the additional compression ratio, resulting from the proposed transformations, using experiments.
