【Abstract】 Simulation analysis has pioneering significance in the engineering design of nuclear technology. Taking the analysis of the Sallen-Key filter hardware as an example, the Multisim simulation software and Excel software VBA function are used to analyze the influence of the four parameters including its own quality factor of the Sallen-Key circuit and the amplitude, pulse width and full width at half maximum(FWHM) on the shape and filtering effect of the output pulse signal, and discuss the optimal parameter design value of the Sallen-Key filter circuit to achieve the ideal Gaussian pulse signal formation. The results show that the simulation analysis method is feasible and provides a good reference for the circuit parameter design of the nuclear electronics course.更多还原
