Abstract
An integrated modular solution for an audio band digital adaptive filter has been designed in LSI technology, which combines independent 240 tap adaptive and programmable FIR filters with coefficient interchange, based on a distributed normalisation architecture. Up to four filter units can be cascaded with optimum performance. Four step-sizes are provided internally with optional further external reduction for application to noisy channels.
