Abstract:A novel model of digital Gaussian filtering is presented in this paper based on Sallen-Key filter. Depending on a second-order differential equation, the authors obtained a general numerical recursive root between the input and the output by applying numerical differentiation algorithm, and implemented digital Gaussian filtering of nuclear pulse signal as well. The operator of the model is confirmed by standard index signal and actual measurement signal simulation.
