Abstract

Method and circuit for regenerating the binary bit stream from a ternary signal In the application P 40 41 717, an improvement in the signal-to-noise ratio with a bit stream regenerator was achieved using a circuit simplified in comparison with the Viterbi detection. The object of the present invention is to make it possible to employ this circuit for a PR4 signal and to increase the transmission reliability.
Two value sequences can be formed by demultiplexing the scanning values of the ternary PR4 signal and these correspond to signals whose impulses are directed alternately positive and negative with respect to a center line. The two scanning value sequences are processed in the time-division multiplex in a circuit corresponding to the older application (Figs. 9 and 10).
In particular for the bit regeneration in a digital video recorde.
