Using the theoretical analysis and numerical simulation, it is proved that a simple nonlinear neuron has the phenomenon of stochastic resonance, and the neuron is used for the transmission of the noisy square wave pulse signal. The results show that this method can effectively improve the signal transmission system Input and output than the gain, thus greatly reducing the signal noise.This paper not only gives a simple neuron model with stochastic resonance, but also extends the application of neurons to the transmission of periodic pulse signals
