Title (EN) FREQUENCY ESTIMATION
(FR) ESTIMATION DE FRÉQUENCE
Abstract:
(EN) A frequency estimator for estimating a frequency, including a counter configured to count an integer number of full clock cycles during a measurement time window; a Time-to-Digital Converter (TDC) configured to measure a fraction of a clock cycle during the measurement time window; and a processor configured to determine the estimated frequency based on the counted number of full clock cycles and the measured fraction of the clock cycle.
(FR) L'invention concerne un estimateur de fréquence permettant d'estimer une fréquence, comprenant un compteur conçu pour compter un nombre entier de cycles d'horloge complets pendant une fenêtre de temps de mesure ; un convertisseur temps-numérique (TDC) conçu pour mesurer une fraction d'un cycle d'horloge pendant la fenêtre de temps de mesure ; et un processeur conçu pour déterminer la fréquence estimée en fonction du nombre compté de cycles d'horloge complets et de la fraction mesurée du cycle d'horloge.
