ASN11 - Our method versus Mark Flower's
Problem Statement
Is our method the same as Mark Flower's? See Wiki. Same # multiply and adds? See Notes 11/3/10.
Response
Mark Flower's paper demostrates to use a filter efficiently. If one wishes to interpolate data, Mr. Flower suggested method is to first apply the filter then perform interpolation. The opposite is done for desimating data; perform desimation then filter. His methods support that it is more efficient in calculation if filtering is done in the stage where the data is the least amount. In Signals and Sytems class, our filtering method for data interpolation and decimation are the same. By choosing to filter before interpolation and after decimation in the class notes, we are also reducing the number of multiply and add operations needed to be done by the filter.
