ULTRASONIC DIGITIZER AND HOST

摘要

A computing system comprises a processor and internal peripheral devices, and a system bus connecting the internal peripheral devices to the processor. One of the internal peripheral devices comprises an ultrasonic digitizer configured for digitization of ultrasonic frequencies and the digitizer digitizes ultrasonic signals from at least two associated microphones into a corresponding digitized audio output and outputs the digitized audio output as a signal on the system bus.
