Abstract
An ideal Schmitt trigger (ST) is the simplest two-state system availab le for realization of stochastic resonance (SR). An exact solution is found for the ST driven by exponentially correlated Gaussian noise plu s a weak periodic signal. The signal-to-noise ratio is shown to pass t hrough a maximum at a specific value of the noise intensity. A qualita tive classification is given for a class of noise models which either exhibit SR or do not.
