Signal processing system for multielectrode sensorial prosthesis. The system comprises a plurality of processing chains CH1,..., CHn each comprising a selective filter FSn, a rectifying circuit Rn, a low-pass filtering stage FPBn and a logarithmic amplifier ALn. This system is characterised in that it furthermore comprises a noise-subtracter circuit arranged between the low-pass filtering stage FPBn and the logarithmic amplifier ALn, a first resistor network ...Rn - 1,n/Rn,n + 1... interconnecting the various chains in the region of the low-pass filtering stages, and a second resistor network ...rn - 1,n/rn,n + 1,... interconnecting the various chains in the region of the logarithmic amplifiers. Application to auditory or tactile prostheses. <IMAGE>
