ABSTRACT:
The invention provides a temperature-insensitive, reflective acoustic wave signal processor employing a trio or reflective arrays disposed effectively to rotate the direction of propagation of the acoustic wave through 180 angular degrees so that the acoustic wave in a preferred embodiment reaches the output transducer flowing in the opposite parallel direction as when launched by the input transducer.
