Abstract
The circuit configuration compensates runtime and pulse-duty-factor differences of two input signals having approximately equal frequency and phase. For each input signal respectively present at an input of the circuit configuration, a signal path is provided that, dependent on the state of the output, is influenced in such a way that the output signal follows the input signal that changes first. A feedback branch with a time-delay element feeds back the output signal to the inputs with a delay, in such a way that these inputs are prepared for the next change of input signal. The delay time of the time-delay element is greater than the maximum chronological deviation between the two input signals.
