还介绍了褶积与逆褶积的数值计算方法，给出了计算公式。
We also introduce the numerical method of convolution and deconvolution, and give the calculation formula.
通常是设计一个逆滤波器，然后与信号进行褶积，目的是使以前的滤波器对信号的影响变为零。
Usually an inverse filter is designed and convolved with the signal, the objective being to nullify an objectionable effect of an earlier filter action.
