Abstract

We present experimental measures of the intermodulation distortion in a static stochastic resonator. The dispositive is basically a Heaviside nonlinearity with adjustable threshold fed with a white noise plus a harmonic test signal. In the stochastic resonance regime, we present experimental results demonstrating a linearization effect. These results are important for signal recovery applications in noisy environments.
