摘要：
We investigated, analytically and by analog simulation, a simple model system, an over-damped Kramers oscillator with two additive noise sources, internal white and external colored. We found that the magnitude of noise background in the spectrum of system output can decrease when the amplitude of external noise or periodic signal increases.
