Design of Cic Compensation Filter for Decimation Filter
This paper presents the efficient modification in the frequency response of CIC compensation filter. The Compensation filter design consist of FIR filter as cascade after CIC filter. . A FIR filter that has a magnitude response inverse of the CIC filter can be applied to achieve frequency response correction . As proposed filter has only three coefficients so less computation is required. The d...
متن کاملCascading Sharpened CIC and Polyphase FIR Filter for Decimation Filter
This paper is concerned with design of cascading CIC filter and FIR filter to improve the passband droop and stopband attenuation for decimation filter. Decimation filter has wide application in both analog and digital systems for data rate conversion as well as filtering. We have three class of filters FIR, IIR and CIC filters. IIR filters are simpler in structure, but not satisfy linear phase...
متن کاملDesign of Modified Three Stage Sharpened CIC Filter for Decimation
This paper presents the design of Sharpened three stage CIC filter for decimation. The proposed decimation filter has Cascaded-Integrator Comb filter as first stage, Sharpened Cascaded-Integrator Comb filter as second and third stage. The CIC filter at first stage operates at input sampling rate, sharpened second stage operates at lower rate as compared to first stage and sharpened third stage ...
متن کاملImplementation and Comparison of Different Cic Filter Structure for Decimation
This paper briefs an implementation of different CIC filter architectures for decimation. The different decimation filter structures are implemented using cascaded integrator-comb filter to work for the down sampling ratio of 8. The prototype is designed with MATLAB Simulink model and it is converted to VHDL code using Xilinx system generator. Prototype is implemented in Virtex VXC5VLX110T-3ff1...
متن کاملDecimation by Non-Integer Factor using CIC Filter and Linear Interpolation
Recently we have developed an efficient flexible multirate signal processing structure with high oversampling ratio and adjustable fractional or irrational sampling rate conversion factor. One application area is a multistandard communication receiver which should be adjustable for different symbol rates utilised in different systems. The proposed decimation filter consists of parallel CIC (cas...
