Application of Pattern Recognition in Waveform Analysis

In accordance with the requirement of waveform auto analysis,the typical waveforms have had fourier transformations from which data are obtainted to form waveform patterns, and further to form typical waveform pattern space. And then, the space pattern recognition method is used to compare the test waveform patterns with the models in the typical waveform space so that the matched degrees are given to the tested waveforms and typical waveforms in terms of disparity degrees whereby determing the types of test waveforms. Also,this paper discusses the application of weighted method of pattern recognition in the test waveforms with noise occured. Finally,the waveform data from practical application are used to carry out analytical tests,indicating that the space pattern recognition method has the better performances in waveform analysis.
