Analogue Adaptive Filters Using Wave Synthesis Technique

Abstract

This paper describes new analogue adaptive filters based on wave synthesis technique. To facilitate simple adaptation process and stability checks, adaptive series and parallel wave adaptors with only one variable coefficient are developed including a suitable algorithm for updating the coefficients of the filter adaptors. A simulation example of system identification is included confirming the viability of the proposed analogue adaptive filters. An efficient hardware implementation of the analogue adaptive filters is outlined.
