基于FPGA分布式算法的FIR滤波器的设计 基于FPGA分布式算法的FIR滤波器的设计-FPGA-based distributed algorithm of the FIR filter design distributed algorithm based on FPGA Design of FIR Filters

用汉宁窗设计一个FIR高通数字滤波器，满足以下参数要求：通带边界频率ωp=0.7π，通带内衰减函数αp=0.4dB；阻带边界频率Ωs=0.4π，阻带内衰减函数为αs=55dB。-With the Hanning window design an FIR high-pass digital filter to meet the requirements the following parameters: passband edge frequency ωp = 0.7π, pass-band at
