The Algorithm Research of Multi-channel MR Band-pass Digital Filters
Because of the spectrum analysis is an important tool to detect the yarn unevenness in Textile industry and the method that spectrum analysis is achieved is to use filters in the industrial field. So there are 55 band-pass filters needed to achieve the spectrum analysis according to the realization algorithm of Ulster spectrometer,thus many problems have appeared with the traditional algorithm,such as the circuit is complex,the ability of anti-interference is poor,and so on,so the reliability and stability of spectrum analysis cannot be guaranteed. As for these problems,this paper puts forward the optimization algorithm to realize the 55 channels IIR filters,and then the optimization algorithm has been simulated based on MATLAB. The results show that the algorithm makes not only the 55 channels filters work properly,but also the computation greatly reduced,and provides a basis for designing of actual system .
