Spectral Contamination Measurement

Authors: Jensen, Deane; Sokolich, Gary

AES Convention 85 · Paper 2725 · November 1988

Abstract

The "spectral contamination" measurement is a graphic spectrum analysis of cross modulation products produced in a nonlinear (any real-world) amplifier or system which is excited by a multi-frequency signal. The system under test is excited at defined frequencies and the resulting nonlinear distortion products are analyzed at other frequencies where no excitation energy is present. It is our hope that this method of measurement will ultimately enable us to correlate objective measurement results with subjective impressions of audio components, a goal which has eluded many traditional distortion measurements.
