Matlab-based Design of IIR Digital Filter
Rui Zheng · Machinery & Electronics · 2011
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.
