We examine the effect of adding a sinusoidal signal to a system of coupled noisy nonlinear oscillators. When the frequency of this "probe" signal is close to the frequency of the unprobed system we observe a resonance behavior, enabling us to determine the underlying frequency of the noisy system. Furthermore, in the prototype SQUID system we consider here, we find that the frequency of the underlying solution decreases with increasing coupling strength. Combining this finding with the resonance phenomenon we discuss ways to enhance the sensitive of SQUIDs to weak low frequency signals.
