In this paper, we proposed the efficient Structure of Multirate filter for decimation process. Now days, decimation is very essential process in many practical applications of digital signal processing. In this case, we introduced three stage decimation filters that performing high decimation process which is generally required in Hearing Aid application, Audio Processing, Noise cancelation and Speech processing. In this paper, implementation of three stage decimation filter is done using the MATLAB Simulink and Xilinx System Generator.

Keywords: Multirate Digital Signal Processing, Multirate Filter, Decimation, CIC Filter, FIR Filter, MATLAB Simulink and Xilinx System Generator.
