ABSTRACT:
A data regenerator is provided which contains a clock regenerator which includes a phase comparator and a clock generator and obtains a sampling clock signal from an input signal, and two sampling devices, a measurement and a sampling device. In both sampling devices, it is possible to adjust the decision threshold and the sampling instants separately. The function of the clock regenerator is not impaired as a result of this. The bit-by-bit comparison of the sampled binary signals yields comparison values which are fed to a controller. The controller determines the optimum decision threshold and the optimum sampling instant from the comparison values.
