Abstarct: FIR filter has many applications in industry. Stability and linear phase are two main of its characteristics. For better efficiency we need to design filter with more coefficiens. FIR filter design involves multi_modal, multi parameter optimization, so different optimization techniques can be utilized to determine the impulse response coefficient of it. By frequency response masking FIR filter structure we can design sharp band pass filter with low computational complexity. And better accuracy for designing FIR filter achieved by combining cultural algorithm and particle swarm optimization algorithm. Systym generator software make it possiable to implant FRM bandpass filter on error FPGA.
