The stochastic resonance (SR) phenomenon for a fractional underdamped bistable system with multiplicative and additive noise driven by one high-frequency and one low-frequency periodic signal is investigated. The Fokker–Plank equation of the system for the low-frequency motion and the transition rate out of the system stable states are obtained. The signal-to-noise ratio (SNR) is derived based on two-state theory. It is shown that bona fide SR and bona fide vibration resonance (VR) phenomenon occur when the SNR varies with the frequency of the low-frequency signal and with that of the high-frequency signal, respectively. Single resonance peak appears when the SNR changes with the increase of the fractional exponent. Damping-induced SR takes place on the SNR curves versus the system damping coefficient. The SNR obtains one maximum value at certain levels of the multiplicative and additive noise.
