Abstract
The invention concerns a method for determining a numerical value for the duration of a periodically repeating pulsed signal. This method comprises the following steps: a) at time intervals, the period length of the signal is determined; b) at time intervals, a characteristic magnitude for the length of a pulse of that signal is determined; c) a numerical value that characterizes the signal is ascertained from the period length and the characteristic magnitude. Because of its shortness and accuracy, the method is particularly suitable for use in electric motors. A corresponding arrangement is also presented and described.
