Matlab-based Design of IIR Digital Filter
摘要
Abstract
Digital filter plays an important role in digital signals. The conventional way have some disadvantages; for example: lower efficiency, complex method and so on. Matlab have a powerful compute,using Matlab can design filters that fixed to the needs quickly, performance parameters can be easily modified and be simulated. It has more advantage compared to the traditional. This paper design a IIR digital filter using the conversion function method of Matlab for the high - speed spindle of 15 000 r/min. The results show that this method has a good reference to the design of the filter. It can be widely applied in the rotor vibration signal preprocessing.关键词
