| 中文摘要 |
| 研究了IDF的频率特性，并与数值微分频率特性、典型微分环节的频率特性进行了比较，然后对其进行了误差分析.通过这一研究，找出了通频带与离散步长△t的挖关系，得出误差与离散步长△t成正比的结论，为其得到更好的应用奠定了基础. |
| 英文摘要 |
| IDF(Inverse Digital Filter )was proposed recently to solve the problem in control. In this paper, we study the fre-quency characteristics of IDF, and then compare it withthat of numerical differentiation and typical differentiator. Enor analysis is also performed. As a result, we fing the approximate relation between discrete step△t and passband, gnd get the conclsion that the error of IDF is proportional to △t. |
