通过计算，可以得到一组滤波器系数h(n)，称为Coefficients。通过h(n)就可以得到FIR滤波器的时域表达式：...
A second order Butterworth IIR low-pass filter was designed as an example. The coefficients required for the standard filter and for the invention are listed below for various ratios of sampling frequency to filter cut-off frequency. Frequency ratioCoefficient a1Coefficient a2Coefficient H0Coefficient ...
