ABSTRACT:
A pulse generator circuit comprises a pulse source and an output line having a specific characteristic impedance and having an input and an output end, the output end being connectable to a high impedance external load and the input end being connectable to and disconnectable from said pulse source. An internal impedance being substantially equal to said characteristic impedance is provided and is connectable to and disconnectable from said input end of the output line. The input end of the output line can be alternatively connected to either the pulse source or to the internal impedance by a switching means. The switching means is controlled by control means in such a way that during delivery of pulses by said pulse source the pulse source is connected to said input end of the output line whereas said internal impedance is connected to the input end substantially during the intervals between the pulses.
