Abstract
In order to adaptively determine the original pulse widths of individual pulses of the pulse signal, there are measured the pulse widths of the distorted pulses. A predetermined number of threshold values is preset for such measured pulse widths. The preset threshold values define classes of pulse widths intended to contain pulse widths of pulses which originally had the same pulse widths. The matching between the measured pulse widths and the preset threshold values is improved by means of a statistical evaluation of the measured pulse widths. The apparatus for carrying out the aforementioned method comprises a unit or circuit for measuring the pulse widths of the individual pulses, a unit or circuit for statistically evaluating the measured pulse widths and a unit or circuit for processing the measured pulse widths.
