摘要：
An idealer bandpassing filter was designed by using wavelet group and analysing ejection acceleration signal spectrum with spectrum zoom method. Compared with FFT spectrum analysis method, the result shows that frequency spectrum zoom method based on wavelet transform has higher frequency resolution rate than FFT spectrum method, moreover, is more simple and easier when performing. It's fit to spectrum analysis whose resolution rate is requested high.
