- 利用理想单位脉冲响应,低通、高通滤波频率在单位脉冲响应下,通过汉宁窗计算理想的截止频带滤波单位脉冲响应-To compute the ideal bandstop filter unit pulse respondence,ideal unit pulse respondence, low/high cutoff frequency, and unit pulse respondence are used in consideration of Hanning windows

- 低通滤波器允许从直流到某个截止频率(fCUTOFF) 的信号通过。将通用滤波器二阶传递函数的高通和带通系数均设为零,即得到一个二阶低通滤波器传递公式-The low pass filter allows the signal to be passed through the DC to a certain cutoff frequency (fCUTOFF). The high pass and band-pass coefficients of the two order transfer f
