| Abstract: | The paper introduces a Single-phase and Single pulse trigger circuit designed by general integrates circuit.This circuit makes use of near-switch and controls integrated trigger triggering.It produces trigger pulse by comparing the!synchronous signal integral with the phase shift signal,and has the ability of resisting synchronous signal high frequency interference and wave distortion.This circuit uses special integrated trigger with lower power consumption,fewer components,strong function,high input impedance,good anti-jamming capability and broad range of phase shift and so on. |
