In this study, a Wavelet Transformation (WT) device of Surface Acoustic Wave (SAW) technology is
developed on the basis of acoustics, electronics, wavelet theory, applied mathematics and semiconductor planar
technology. The Finger Reflection (FR) error is the primary reason for this kind of device. To solve the problem, a
mathematic model of Littlewood-pelay wavelet was established first, which is matched with the model of SAW.
Using the methods of split finger and fake finger to design IDT of Littlewood-pelay WT device of SAW with L-edit
software, the FR error can be reduced and the equivalent construction of IDT is simulated.
Key words: Finger Reflection (FR), Interdigital Transducer (IDT), l-edit software, littlewood-paley WT, Surface Acoustic Wave (SAW), ,
