Janusz M. Mosakowski, Andrzej Podgórski

Abstract

Set of filters is required for the analysis of sound and vibration signals usually composed of different elements. The designing process of so-called 1/1 octave and 1/3 octave digital filters and their implementation in the digital signal processor, working in the real time system, is shortly presented. The obtained exemplary frequency characteristics are given.
