The concepts of digital signal processing are playing an increasingly important role in the area of multirate signal processing, i s . signal processing algorithms that involve more than one sampling rate. In this paper we present a tutorial overview of multirate digital signal processing as applied to systems for decimation and interpolation. We fmt discuss a theoretical model for such systems (based on the sampling theorem) and then show how various structures can be derived to provide efficient implementations of these systems. Design techniques for the linear-time-invariant components of these systems (the digital fdter) are discussed, and finally the ideas behind multistage implementations for increased efficiency are presented
