Moving Average Filter Design Using MATLAB

Abstract

Need for signal processing and filtering are as old as electronic engineering itself, but recent developments in telecommunications, multimedia, and modern warfare have pushed design requirements to before unknown levels. Quest for more bandwidth, better sound definition and better video compression has fuelled significant new developments in filter designs. Starting point for any aspiring electronic engineer is learning to use industry-standard MATLAB software package and exploring its numerous uses in signal processing and filter design. Here MATLAB is used to design one of the most needed digital filters nowadays, the Moving Average filter the design is built based on characteristic equations and Z-transform.
