PCT No. PCT/FI94/00525 Sec. 371 Date May 22, 1996 Sec. 102(e) Date May 22, 1996 PCT Filed Nov. 24, 1994 PCT Pub. No. WO95/15030 PCT Pub. Date Jun. 1, 1995The present invention relates to a method and device for symmetrizing a clock signal. The leading or trailing edge of each pulse of the clock signal (Fin) to be symmetrized is used for forming the first edge of the pulse of the corresponding symmetrized clock signal (Fout). The pulse ratio of the symmetrized clock signal is measured; and on the basis of the measured pulse ratio, the time constant circuit (R1, C1), determining the location of the second edge of the pulse of the symmetrized clock signal, is adjusted by means of a control loop (R6, C2, A) in such a manner that the second edge of the pulse of the symmetrized clock signal (Fout) settles in a desired position in the symmetrized clock signal.
