The Research of Wavelet Transformation Technology by Using Surface Acoustic Wave Devices

The developing of wavelet transformation device of SAW (Surface Acoustic Wave) made the wavelet transform get rid of the situation, which could not be universally applied affected by complex algorithms. Because of the production expenses of wavelet transformation device of SAW is so expensive, now researchers require using software to pretest the performance of the device. This article discusses the way combining SAW technology and wavelet transform theory, to achieve wavelet transform by using the SAW devices, learn and master the Pspice software, then design interdigital transducer and equivalent circuit of Morlet wavelet to meet the requirements of the actual circuit. Using wavelet transformation device of SAW to achieve wavelet transform and to simulate by Pspice will be a new direction of the area in SAW research. There will be much more room for the development and practical application.
