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]
