  • Noise rejection in a sonic transducer
    Patent number: 4721902
    Abstract: A method of time domain noise rejection in a sonic transducer is disclosed in which all signal reception is prevented between application of a periodic electrical pulse and reception of the corresponding electrical signal. An inhibit signal, produced for a substantial portion of the time interval between application of an electrical pulse and reception of the corresponding electrical return signal, blocks all noise that may occur to provide a false indication of a return electrical signal during the time of the inhibit signal.
