We study the stochastic resonance phenomenon in the nonlinearly coupled Langevin equations with Gaussian noise and driven by different external periodic forces. We consider (i) sine, (ii) square, (iii) symmetric saw-tooth, (iv) asymmetric saw-tooth, (v) modulus of sine and (vi) rectified sinusoidal forces. Stochastic resonance is observed in the presence of(More)
