ABSTRACT:
The invention relates to a receiver arrangement for a push-pull transmission method. First and second signal detectors, to which a first input signal is fed provide first and second detector signals depending on a comparison of the first input signal with a detector threshold. Third and fourth signal detectors, to which a second input signal is fed provide third and fourth detector signals depending on a comparison of the second input signal with a detector threshold.The first and third detector signals are respectively fed to a data input of a first and second buffer store. The second and fourth detector signals are respectively fed to a reset input of the first and second buffer store. The first and second buffer store are designed for buffer-storing signal pulses contained in the first and second detector signals and forwarding them to a respective output for subsequent further processing in time-delayed fashion after a first delay duration.
