Abstract
A synchronizing, pick-off type circuit for use with underground detection systems of a variety utilizing a high voltage pulse generator generating pulses by dielectric breakdown over a gap and evidencing a sustained and discernable substantially lower voltage level for a short interval following the pulse. Pick-off is derived by tapping a transmitting coaxial cable with a "T" connection carrying a choke inductor and a resistor, each of which is coupled to the central conductor of the coaxial cable and which are mutually connected in parallel circuit relationship.
