Abstract :
The advantages of an admittance formalism for the derivation of performance characteristics of transversal filters and one-port information stores using acoustic surface-wave delay lines are described. An expression for the transadmittance between transducer pairs in the weak-coupling approximation is derived using a normal mode theory. The formulation is found to give good agreement with measurements of the passband response of a wide-band logarithmically frequency-tapered transducer pair on YX-quartz. A brief discussion of the limitations of the model is included.
