Ultrasonic Circuits Circuits

40Khz Ultrasound Receiver - A X100 transistor amplifier is followed by a zero cross detector circuit, using a voltage comparator. The output is a TTL logic signal, corresponding to the received 40KHz signal . . . [Circuit by Dave Johnson P.E., 01/29/06]

40Khz Ultrasound Transducer Driver uses Medium Power - This crystal controlled circuit drives a 40KHz piezo transducer with a 30v peak to peak signal . . . [Hobby Circuit designed by David Johnson P.E., 01/29/06]
