ThePaper Presents efficient implementation of downsampler and upsampler using Multirate digital signal processing system which includes sampling rate conversion.The adder which is used in down and upsampler is replaced by modified carry select adder and the circuit obtained is verified and compared successfully to show low power and area consumption and the same is implemented for tunable band pass filter.A noised input speech signal is denoised after filtering in the multirate filter application.Reduction of power and area is important for VLSI system and also it becomes one of the most critical design parameter.
