Abstract

2.1.In Application P 40 41 717, an improvement of the signal/noise ratio in a bitstream regenerator is achieved with a circuit simplified compared with the Viterbi detection circuit. It is the object of the present invention to enable this circuit to be used with a PR4 signal and to increase the reliability of transmission. 2.2.By demultiplexing the samples of the ternary PR4 signal, two sequences of values can be formed which correspond to signals, the pulses of which are alternatively directed positively and negatively with respect to a centre line. The two sequences of samples are processed in time-division multiplex in a circuit corresponding to the prior application (Fig. 9 and 10). 2.3.Particularly used for bit regeneration in a digital video recorder. <IMAGE>
