Abstract:
1. A receiver circuit for a push-pull transmission method, comprising: at least one first input for receiving a first input signal; at least one second input for receiving a second input signal; an output providing an output signal dependent on the first and second input signals; a detector circuit having a first signal detector connected to said first input and a second signal detector connected to said second input, said first and second signal detectors comparing amplitudes of the first and second input signals in each case with a detection threshold and providing detector output signals including a first detector output signal from said first signal detector and a second detector output signal from said second signal detector, said first and second signal detectors each having a control input for setting the detection threshold to at least a first value and a second value lower than the first value, said control input of said first signal detector being coupled to an output of the second signal detector and said control input of said second signal detector being coupled to an output of said first signal detector; and a signal processing circuit connected to said detector circuit and receiving the detector output signals, said signal processing circuit generating the output signal according to the detector output signals; after an amplitude of one of the first and second input signals exceeds the first value of the detection threshold, the detection threshold compared to another one of the first and second input signals being decreased to the second value of the detection threshold.
