发明名称 Linear voltage-pulse base-clipping circuit with adjustable-threshold condition and echograph comprising such a device
摘要 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. The first line transmits the signal suitably delayed by means of an adjustable delay line to an attenuator which is controlled by the second control line which provides, depending on the threshold condition, the adjustment of the transfer of the attenuator.
