1981年第3期《电子技术应用》上介绍的“组合波干扰的快速图解法”一文,给出的图解组合波干扰点的分布,共特点是不容置疑的。但有些问题的处理,文章中介绍的方法,似乎有些繁琐与重复。本文就此提出几点看法。例如“n 个问题的讨论”中关于在m=0这条直线上丢失干扰点问题的讨论,就是这样。我认为文章中已经定义了A=f_n/f_c,B=f_n/f(?),这就没有必要再引出A′=f_n/f_r 这个量了。对取和频的情况来说,当把f_c 作输入时,就在
1981, No. 3 “Application of Electronic Technology,” the introduction of “composite wave interference fast graphic method” article, given the combination of wave interference point distribution, the total characteristics are beyond doubt. However, some problems, the methods described in the article, it seems a bit cumbersome and repetitive. This article made a few comments on this point. This is the case, for example, in the discussion of n questions about the loss of interference points on the line m = 0. In my opinion, we have defined A = f_n / f_c and B = f_n / f (?), So there is no need to derive A ’= f_n / f_r. In the case of sum and frequency, when f_c as input, there
