Abstract – The desensitized FIR  filter using Vedic multiplier is presented to achieve higher operating speed. Vedic mathematics utilizes less computation time. The performance of proposed desensitized filter using Vedic multiplier is compared with conventional filter using array multiplier. The evaluation carried out through simulation and functional verification in order to highlight the speed superiority by reducing the computation time. The simulation and analysis is done by using Modelsim 10.1b and synthesized using Xilinx ISE 9.2i.

Keywords— Desensitized FIR  filter; Vedic multiplier; Array multiplier; Multirate systems
