| 摘 要： | 介绍一种模糊自动控制滤波器原理及其在时域信号处理中的应用。讨论了滤波器的滤波效果与模糊控制参数间的关系，提出了一种利用表征测量信号波形的短时分形维数来修正滤波器的模糊控制系统，从而改善模糊滤波器对噪声滤除效果的方法，计算表明其滤波效果远优于模糊控制滤波参数α固定的滤波效果。

| Abstract: | This paper presents the principle of Fuzzy Control Digital filter and its application in human voice related to signal processes and discusses the relationship between the filter processing result and its control parameter. To improve this filter, a new method called form division dimension is presented to automatically adjust the value of the filter's control parameter based on the measurement of waveform and its noise pattern. Compared with the outputs, the one with adjustment function performs much better than the one without it. |
