Abstract

A trigger circuit comprises a shaping circuit connected between an input terminal receiving a trigger signal and an avalanche transistor. The shaping circuit has a pass band whose upper limit frequency is much lower than the frequency component of the leading edge of the input trigger signal, and it has a saturation characteristic to provide a pulse whose time width is sufficient to start the avalanche transistor.
