ABSTRACT:
A binary data signal is regenerated with respect to three threshold levels, one of which is derived from and lies between the other two so that it is an optimum level for producing a regenerated output signal. Two control loops are used to produce the other two threshold levels to produce regenerated signals with predetermined error rates, the errors occurring on the two control loops for the two respective states of the binary data signal, whereby the optimum threshold level is maintained regardless of the nature of signal degradation. The arrangement provides rapid performance monitoring which can also be used to adjust other parameters, such as detector bias, equalizer tuning, and clock phase, for optimum performance in an active and ongoing manner.
