After an introduction to the principle of fuzzy-control digital filter and its application in time-domain signal processing
the relationship between the filter processing result and its fuzzy-control parameters has been discussed in this paper.To improve the filter processing effect
a new method called short-time fractal dimension has been presented to adjust the value of the filter′s fuzzy-control parameter.Filtering of the Weierstrass function shows that this method is an effective filtering method and can be widely used for the filtering of complex signals.
