Abstract :
In this paper we analyze method for the design of the optimized multistage decimation filter chain based upon the minimization of computational load. Decimation ratios for each of K stages are obtained with respect to the optimal number of FIR filter multiplications. We evaluate performances of the optimized multistage filter chain for two and three stage cases and compare the obtained results with single stage decimation structure. Performances are measured by using number of multiplications per output sample.
