A bistable cubic map is used as the model and we show that it combines the features of a bistable system and a threshold system. A study of stochastic resonance in these two setups reveal some fundamental differences between the two mechanisms with respect to amplification of a composite input signal. As a practically relevant result, we show that the phenomenon of stochastic resonance can be used as a filter for the detection/transmission of the component frequencies in a composite signal.19 pages, 12 figures. submitted to Physica ScriptaChaotic Dynamicstext
