Experimental Performance Measurements of Adaptive Noise Canceller (ANC). Various Inputs and Internal Parameters Correspond with Existing Theory.

Abstract

This report describes tests performed on the Adaptive Noise Canceller (ANC) as part of a joint NUSC/NOSC program investigating adaptive processors. The purpose of the test was to evaluate the effects of various inputs and internal parameters on the operating characteristics of the ANC. The primary dependent parameters of interest were the adaptive time constant, the notch width, and notch depth. These were measured as functions of the filter length, feedback constant, reference power spectrum and delay. The number of reference inputs was varied as well. The experimental results are plotted and show excellent agreement with existing theory. (Author)
