Patent ID: 7085685

Claim:
A device to filter electrical signals, having a number of input terminals arranged spatially at a distance from one another to supply respective pluralities of input signal samples, and a device output terminal to supply a plurality of filtered signal samples, the device comprising: a number of signal processing channels, each signal processing channel being formed by a neuro-fuzzy filter to receive a respective plurality of input signal samples and to generate a respective plurality of reconstructed samples; an adder unit to receive said plurality of reconstructed samples and having an output terminal to supply said plurality of filtered signal samples; and routing means coupled to said output terminal of said adder unit and controllable so as first to supply said filtered signal samples back to said signal processing channels, then to supply said filtered signal samples to said device output terminal, wherein each signal processing channel includes; a sample input terminal to receive alternately said input signal samples and said filtered signal samples and to supply signal samples to be filtered; a signal feature computing unit to receive a respective plurality of samples to be filtered and to generate signal features; a neuro-fuzzy network to receive said signal features and to generate reconstruction weights; and a signal reconstruction unit to receive said samples to be filtered and said reconstruction weights and to generate said reconstructed samples from said samples to be filtered and said reconstruction weights.
