Abstract
Method and apparatus for the error-free synchronization of asynchronous pulses through logical interconnection of the asynchronous pulses with clock pulses of constant frequency by means of a flip-flop, which includes comparing output voltages of the flip-flop with a predetermined threshold voltage for determining a metastable state of the flip-flop, and flipping the flip-flop into a third stable state until the next clock pulse appears if a metastable state is present, for preventing an evaluation of the output voltages of the flip-flop.
