基于Matlab GUI的FIR滤波器
说明: 基于Matlab GUI的FIR滤波器
实际中,一般调用MATLAB信号处理工具箱函数remezord来计算等波纹滤波器阶数N和加权函数W(ω),调用函数remez可进行等波纹滤波器的设计,直接求出滤波器系数。函数remezord中的数组fedge为通带和阻带边界频率,数组mval是两个边界处的幅值,而数组dev是通带和阻带的波动,fs是采样频率单位为Hz。(FIR filter based on matlab gui. In practice, the MATLAB signal processing toolbox function remezord is generally called to calculate the order N of the equiripple filter and the weighting function W . The call function remez can be used to design the equiripple filter and directly calculate the filter coefficients. The array fedge in the function remezord is the pass-band and stop-band boundary frequencies, the array mval is the amplitude at the two boundaries, the array dev is the fluctuation of the pass-band and stop-band, and fs is the sampling frequency unit in Hz.)
