%X The odd multiple frequency phenomenon emerging in the stochastic resonance was studied, and some new theoretical conclusions was drawn. Based on these conclusions we found the reference frequency which must be set in the chaotic detector. Using the frequency selectivity of chaotic detector, the false frequency existing in the odd multiple frequency was filtered out.
