Research on Virtual Instrument for Wavelet Transform

The scheme for designing virtual instrument of wavelet transform is described. Mathematic model of wavelet analysis function and typical controls is founded and the algorithm is selected and designed. Based on virtual instrument technology, the virtual instrument of wavelet transform is successfully developed. The instrument consists of continuous wavelet transform, discrete wavelet transform, wavelet package decomposition etc, which provide the engineering signal analysis a new manner. The fact is proved, the instrument has extensive using value.
