Design of a programmable digital filter

In recent years, digital filters for the processing of signals have developed rapidly. The aim of this project was to study the design and implementation of digital filters in terms of hardware, rather than by software programming of a general purpose digital computer. A digital filter has been designed and built with 8 bit accuracy intended as part of a high order filter. It is intended to perform as a lowpass, highpass or bandpass filter by multiplexing and frequency transformation.
