In this paper four proposed structures for the digital decimation filter which is used in converters of Asymmetrical Digital Subscriber Line (ADSL) are presented. Single multi rate (Finite Impulse Response) FIR, single multi rate (Infinite Impulse Response) IIR, three stages comb-FIR-FIR and comb-IIR-FIR are the four proposed structures. The hardware minimization is considered for each structure. The simulation results and the implementation of each structure are presented. Finally, a comparison between the four proposed structures is done to choose the best proposed structure based on the hardware cost.
