ABSTRACT:
A SAW substrate is disclosed which can be adapted to a particular signal in multitude of signal possibilities. Each signal adaptation is made by connecting alternate electrodes of sequential tap transducers to either a positive bus or a negative bus, through auxiliary buses. A pair of the auxiliary buses is dedicated to each tap transducer, with one auxiliary bus in each pair being disposed adjacent to the positive bus and the other auxiliary bus in each pair being disposed adjacent to the negative bus. A pad is associated with each auxiliary bus for locating it adjacent to the positive bus or the negative bus which is not otherwise adjacent thereto. When a large number of signal possibilities are necessary, an unreasonably lengthy substrate is avoided by aligning the tap transducers in parallel channels across the substrate.
