A new type of electronic receiver based on stochastic resonance properties is proposed to retrieve subthreshold modulated (or not) digital signals. In order to check the receiver performances, we investigated different kinds of modulations. Considering both uniform and Gaussian white noise, a total restoration of the emitted data is achieved for an unmodulated or amplitude modulated (AM) signals, while an almost total restoration is reached using a frequency shift keying (FSK) modulation. These experimental results confirm the great interest of stochastic resonance in the signal transmission field.
