摘要：

An electronic circuit was designed to observe doubly stochastic resonance (DSR) and noise-induced phase transition. The input current, a time varying resistor (TVR), and a nonlinear resistor were used in the circuit. The signal to noise ratio was calculated by extracting the power spectral density and taking the ratio of signal and noise. The results were verified by performing simulations of model using numerical methods.
