PCT No. PCT/DE94/00108 Sec. 371 Date Aug. 29, 1994 Sec. 102(e) Date Aug. 29, 1994 PCT Filed Feb. 4, 1994 PCT Pub. No. WO94/18754 PCT Pub. Date Aug. 18, 1994A device which reshapes sinusoidal signals with a singularity to generate square-wave signals and detects the singularity in an unambiguous and reliable manner. The sinusoidal pulses are reshaped into square-wave pulses in such a way that the edges of the square-wave pulses always occur at the same location regardless of the height of the sinusoidal signal. This is achieved in that a change in the edges of the square-wave signals is initiated whenever the sinusoidal signal crosses the zero-axis. The required signal processing and logical comparisons, which also enable a definite detection of reference marks, are carried out in a suitable circuit arrangement.
