The converter circuit has an exclusive OR (3) gate of which the output is connected simultaneously to a clock input (CK) of two type D flip-flops. A clock input of the type-B flip-flop is connected directly to one input of an exclusive OR gate. The second type D flip-flop (4) acts as a divide-by-two circuit and its outputs (Q, QN) provide the outputs of the type B flip-flop (1). The sum of the propagation times of the first flip-flop (2) and of the exclusive OR gate (3) is less than half the minimum duration of the pulse to be sampled. The circuit is embodied as a single discrete component integrated on a chip.
