METHOD AND APPARATUS FOR DETERMINING THE CHANGE IN FREQUENCY OF A REFERENCE SIGNAL

A method for determining the change in frequency of a clock signal (168). The method includes the step of counting the number of clock signal cycles (168) that occur over at least two time windows (162, 164). The number of clock signal cycles counted in the first time window (162) is compared to the...

Zusammenfassung:A method for determining the change in frequency of a clock signal (168). The method includes the step of counting the number of clock signal cycles (168) that occur over at least two time windows (162, 164). The number of clock signal cycles counted in the first time window (162) is compared to the number of clock signal cycles counted in the second time window (164). L'invention porte sur un procédé permettant de mesurer les variations de fréquence d'un signal d'horloge (168) consistant à compter le nombre de cycles du signal d'horloge (168) pendant au moins deux créneaux de temps (162, 164), le nombre compté dans le premier créneau (162) étant comparé à celui compté dans le deuxième créneau (164).
