Parameter detection for surface acoustic wave filter based on image processing

As core tools for the smart device RF front end, surface area acoustic wave filters remain in brief supply. The discovery of SAW filter parameters refers to the link between layout style and procedure production, which is an integral part of ability improvement. This paper devises a method based on photo processing to find SAW filter parameters. We improve the morphological driver to recover a picture and identify the number of interdigital transducer finger bars under sound problems. The speculative outcomes reveal that the number of IDT finger bars is precisely identified.
