  • Linear voltage-pulse base-clipping circuit with adjustable-threshold condition and echograph comprising such a device
    Patent number: 4470017
    Abstract: The present invention relates to a linear voltage-pulse base-clipping circuit with adjustable-threshold condition.It comprises, for unipolar signals, two lines in parallel.
