Additional Description

Abstract

The design of an adaptive filter to remove feedback noise from a public address system was attempted. The ADSP-2111 digital signal processor chip was used to implement this filter. The least mean squares adaptation algorithm was implemented in the software. Programs were developed to both pass an unmodified signal and to filter the signal for the removal of the noise. Possible reasons for the failure of this project to achieve its objective are given in the conclusion.
