Influence of heavy data transmission losses on spectra of signals

Abstract

Measurements of machine vibrations are often influenced by heavy data losses during wireless transmission of signals, which arise because of electromagnetic interference of electric motors. In this paper, authors present an analytic calculation of distortions introduced in spectra of harmonic signals by heavy data transmission losses, which are characterized by the loss ratio and frequency of losses. The results may be used to reduce errors that arise during spectral analysis of signals in conditions of heavy spectral losses. © (2013) Trans Tech Publications, Switzerland.
