Surface acoustic wave type electrode‐area‐weighted wavelet inverse‐transform processors with phase compensation
The main purpose of this research is to investigate a novel implementation method for a surface acoustic wave type (SAWT) electrode‐area‐weighted (EAW) wavelet inverse‐transform processor (WITP). The method of EAW is that the electrode areas of the input and output interdigital transducers (IDTs) ar...

| description | The main purpose of this research is to investigate a novel implementation method for a surface acoustic wave type (SAWT) electrode‐area‐weighted (EAW) wavelet inverse‐transform processor (WITP). The method of EAW is that the electrode areas of the input and output interdigital transducers (IDTs) are proportional to the envelope areas of the wavelet function (i.e. the two IDTs are identical). By this method, the SAWT EAW WITP is fabricated on X‐112°Y LiTaO3 substrate material. In the study, the diffraction problem and phase difference as two key problems are presented and the solution to two problems are implemented. |
