Claim 7:
8. A non-transitory computer-readable medium for determining an incident angle of an acoustic wave and storing instructions that when executed by one or more processors cause the one or more processors to analyze N voltage signals output by N coupled analog circuits that solve a set of N coupled differential equations modeling a set of N virtual coupled acoustic resonators to produce an estimate of the incident angle of the acoustic wave, wherein:
N is a natural number greater than or equal to 2;
each of the N coupled analog circuits receives an output signal from a unique one of N transducers that receive the acoustic wave; and
each of the N coupled analog circuits outputs one of the N voltage signals.
