ABSTRACT:
The invention involves a self-adjusting equalizer configuration which automatically adjusts to the cable length. The equalizer configuration has band limitation for the transmission of digital signals and consists of an equalizing amplifier, a correction filter, and an amplitude control loop with a comparison of actual and nominal values. The object of the invention is to specify a circuit in which the correction filter is not located in the signal path. This object is achieved in such a way that the equalizing amplifier is located in the signal path, and the correction filter is placed in the amplitude control loop so that the output signal of this correction filter represents the actual value for the amplitude control loop.
