A microprocessor-based digital filter laboratory station for an undergraduate signal processing laboratory

A microprocessor-based digital filter laboratory station to provide hands-on experience to the students in the design of digital filters is described. The unit is centered around an 8080A microprocessor which can be employed programmatically by the user to interconnect the various modules comprising a digital filter and to experimentally evaluate their characteristics. This flexible laboratory station allows the student to conduct a variety of experiments in the fundamentals of digital signal processing and introductory digital filter design based on the Peled-Liu (Croisier et-al) algorithm.
