Control Methods for Sigma-Delta Based Audio Equalizers

Document Thumbnail

In this paper we discuss real-time control of the parameters in an improved structure for implementing one-bit signal processing, in particular the problem of parameter interpolation. The problems of current approaches are reviewed and an analysis of the effects caused by controlling these structures presented. We show that this form of control is benign in both stability and intermediate frequency responses.
