| Abstract: | Virtual instrument has taken the lead of the profession of test instrument. LabVIEW is a kind of developing flat of virtual instrument with powerful function.Wavelet transform is an important way to study signal in time-frequency domain.The main content of the paper is to put up the 2nd development of LabVIEW, enlarge the analytic function of wavelet and wavelet packet , make use of them to deal with nonstationary random signal, and compare wavelet analysis with traditional Fourier transform. |
| Keywords: | Virtual instrument LabVIEW Wavelet transform Wavelet packet analysis |
