We consider two bistable systems, the double-well potential and the Schmitt-trigger, and examine whether the stochastic resonance occurring, in these systems may produce output signals less noisy than the input. We apply cross-spectrum and cross-correlation based generalised measures to quantify noise content in the input and output, which enables us to use aperiodic or random sequences as input signals. We show that input-output signal improvement occurs even for these types of input.
