By simulating the frequency behaviors of the input thresholds in a bistable system and a Hindmarsh Rose neuron, respectively, we study how the input thresholds depend on the frequency of input signal in both non excitable and excitable nonlinear systems in which stochastic resonance may appear. We also present an approximate approach to get the frequency characteristics of input threshold analytically and analyze the unusual minima of the frequency characteristics in excitable systems.
