EFFICIENCY ESTIMATION CRITERIA OF LOSSY COMPRESSION METHODS OF MEASUREMENT SIGNALS

Waclaw Gawedzki, Jerzy Jurkiewicz
Abstract:
The paper presents problems of compressing measurement signals recorded under long-lasting monitoring conditions. The criteria for compression method selection in view of its efficiency (compression ratio) and quality of conversion (coding-decoding procedure), with regard to dynamic properties of the measurement signals are discussed. Attention is given to the interdependence of the achieved compression ratio and the distortion level. A method is proposed for generating synthetic test signals to investigate the efficiency of lossy compression methods, which enables unification of the achieved results.
