Abstract: Systems and methods for virtually coupled resonators to determine an incidence angle of an acoustic wave are described herein. In one example, a system includes a processor and first and second transducers in communication with the processor. The first transducer produces a first signal in response to detecting an acoustic wave, while the second transducer produces a second signal in response to detecting the acoustic wave. The system may also include a memory in communication with the processor and having machine-readable instructions that cause the processor to modify the first signal and the second signal using a virtual resonator mapping function to generate a modified first signal and a modified second signal. The virtual resonator mapping function changes the first signal and the second signal to be representative of signals produced by transducers located within a hypothetical chamber of a hypothetical resonator.

Abstract: A programmable delay device that provides delays of more than 100 ns over a broad bandwidth is disclosed. The device includes an input stage that employs M sampling switched capacitor elements such that each sampling switched capacitor element samples at a rate of only 1/M of the fundamental sampling rate. The device includes a programmable delay stage with M programmable switched capacitor banks, each programmable switched capacitor bank having N delay switched capacitor storage elements. Thus, the programmable delay stage includes a total of M×N delay switched capacitor storage elements, thereby reducing the sampling rate by a factor of M×N. This reduced sampling rate permits much smaller sampling switches, resulting in reduced leakage current and enabling far longer programmable delay times. Lastly, the device includes an output reconstruction stage that reconstructs a delayed version of the input RF signal by combining signals from the programmable delay stage.
