ABSTRACT:
In an apparatus for detecting input digital data, for example, as derived by analog-to-digital conversion of a reproduced binary signal in analog form; a distributor circuit distributes the input digital data into at least two channels, a processing circuit in each channel processes the respective digital data in accordance with a predetermined formula, a decoder in each channel decodes an output of the respective processing circuit in accordance with the Viterbi algorithm, and the outputs of the decoders are composed or combined to provide therefrom a single sequence of digital data.
