Abstract
An apparatus (300) for detecting an ultrasonic signal (304) has a transducer (302) that produces an electrical signal (306) in response to the ultrasonic signal (304). A threshold comparator (308) receives the electrical signal (306) and produces a phase one signal (310) and a phase two signal (312). An arming circuit (314) receives the phase one signal (310) and the phase two signal (312) and producing an arming signal. A triggering circuit (316) receives the arming signal and the electrical signal (306) and produces a signal detected signal (318).
