Surface Acoustic Wave Bidirectional Filter Synthesis And Analysis, Raymond L. Yap
Retrospective Theses and Dissertations
Surface Acoustic Wave (SAW) devices are manufactured using standard metallization and photolithographic techniques that have been established by the semiconductor industry. The facilities in the newly developed Microelectronics laboratory at the University of Central Florida will be utilized in the fabrication of a SAW device.
This thesis will outline the complete procedure beginning with the initial design from given specifications, up to mask generation, fabricating and testing of the device. This will serve to calibrate the fabrication process for future work in SAW device and semiconductor fabrication.
The models that are used in the SAWCAD design software will be verified …

Non-Iterative Finite Impulse Response Design Techniques, Carlton D. Bishop
Retrospective Theses and Dissertations
A general, non-iterative design technique for low shapefactor, transversal filters is presented. This design approach uses two cosine series to specify appropriate eigenfunctions. An infinite set of such eigenfunctions are defined and the method for choosing the coefficients is discussed.
The total filter response is specified as the product of two individual frequency responses. The impulse response of each is then determined by applying the superposition of appropriate eigenfunctions. The criteria for choosing the appropriate eigenfunctions is discussed.
A synthesis procedure for designing surface acoustic wave filters is presented. The effects of truncating the impulse response are also explored. A …
