Abstract

Multirate signal processing is out of the unique advantages of discrete-time signal processing in the domain of signal processing. The area of multirate signal processing is very broad. It includes basic topics such as decimation system and interpolation system, and more involved topics such as perfect reconstruction filter banks and wavelets. If higher sampling rates are required to display digital wave- form for D/A convertor, then an interpolation sys- tem can be used. However. a fundamental idea in the area of multirate signal processing is that one should always perform computations at the lowest possible sampling rate. In our case, we are only considering the interpolation system. Therefore, other multirate signal processing approaches are omitted herein.
