Design And Implementation Of A Microprocessor Controlled Digital Filter

Abstract

The construction and implementation of a microprocessor controlled real time recursive digital filter have been given. The system designed could also be applied to a variable coefficients system such as ADAPTIVE FILTER and it makes use of a programmable LSI digital filter and detect "FAD" chip. High flexibility of such system has been proved by the realization of recursive IIR filter with different types and different orders. A wide sampling ranges could be achieved by altering the clock frequency of the filter.
