    Abstract: A system (10) for decoding digital signals subjected to block coding (B) comprising a post-processor (13) which corrects (13) the codewords affected by error, identifying them with the most likely sequence which is a channel sequence and which satisfies a syndrome check. The post-processor (13) is a finite-state machine described by a graph (G) which represents the set of error events (E), the set of respective transitions defining the structure of said set of error events. Preferably, the post-processor (13) evolves in steps through subsequent transition matrixes (G), deleting at each step the following graph paths

    paths which accumulate an invalid number of error events (N E ) or an excessive number of wrong bits (N),
    paths which accumulate a total reliability higher than a given threshold (β),
    paths with a invalid check on the received sequence (P), and
    paths which reveal an invalid syndrome (S) after having reached a maximum number of events.

    Abstract: The invention relates to a non-linear electronic device and, more particularly, to a non-linear capacitor.
    More specifically, but not exclusively, the invention relates to an electronic circuit device that may be integrated on a semiconductor substrate. Advantageously, the non-linear device is a capacitor formed by a feedback loop of cascade connected active blocks (2, 5, 6). Moreover, the invention may be integrated or used in association with a circuit network including other non-linear devices.

    Abstract: The invention relates to a time-continous FIR (Finite Impulse Response) filter whereby a Hilbert transform can be implemented. The filter comprises a cascade of delay cells connected between an input terminal of the filter and an output terminal; constant filter coefficients (cO,...,cn) and a programmable time delay (Td) of the programmable filter cells are provided.
    The invention also relates to a filtering method effective to enable use of this Hilbert FIR filter structure for processing signals originated by the reading of data from magnetic storage media which employ perpendicular recording.
