AN ADAPTIVE ALGORITHM FOR THE MEASUREMENT DATA COMPRESSION

W. Gawedzki

Abstract

A proposal for a lossless adaptive compression algorithm to be used in continuous measurement data recording is presented in this paper. The operation implemented by the algorithm can be termed the signal compression before quantization. Although the algorithm itself is inertialess, its efficiency depends on the dynamics of the measurement signal compression. Thanks to the adaptation of the compression algorithm parameters to the variability characteristics (i.e. to the dynamics) of the signals recorded, the compression level can be optimised. The algorithm, method for the adaptation of the algorithm parameters and the compression effect obtained for exemplary measurement signals are presented in this paper.
