Abstract :
We present an analogy between FM modulation and stochastic resonance and a stochastic resonance (SR) condition from that analysis. The SR is possible when there is no signal harmonic distortion at the FM demodulator output. The non-THD condition is experimentally demonstrated with an ad-hoc test bench and an algorithm, implemented as a virtual instrument, for SR tuning is also shown. A THD characterization of stochastic resonance let to use digital filtering for tuning the optimal noise level.
