Abstract
(DE)
Das erfindungsgemäße Verfahren sieht die Schritte vor: Bestimmen eines zeitlich gemittelten Maximalwertes, welchen die Leistung der Hochfrequenzabstrahlung des getakteten Systems (21) in einem vorgegebenen Frequenzband nicht überschreiten soll; Modulieren einer Oszillationsfrequenz des anregenden Oszillators (22) mit einem Frequenzhub, derart dass die mittlere Leistung in dem vorgegebenen Frequenzband unterhalb dem Maximalwert liegt; Bestimmen einer Bandbreite (B) eines Funkempfängers und Modulieren der Oszillationsfrequenz (fT) mit einer Modulationsfrequenz (fM), welche größer als die Bandbreite des Funkempfängers ist.
(EN)
The invention relates to a method for damping a high-frequency radiation of a clocked system consisting in determining an average maximum time value which is not exceedable by the power of the clocked system (21) high-frequency within a predetermined frequency band, in modulating an oscillator (22) oscillation frequency with a frequency deviation in such a way that the average power is lower than the maximum value within the predetermined frequency band and in determining a bandwidth (b) of a radio receiver and modulating an oscillation frequency (fT) with a modulation frequency (fM) which is greater than the radio receiver bandwidth.
(FR)
L'invention concerne un procédé d'atténuation d'un rayonnement haute fréquence d'un système cadencé, ce procédé comprenant les étapes suivantes : détermination d'une valeur maximale à moyenne temporelle que la puissance du rayonnement haute fréquence du système cadencé (21) ne doit pas dépasser dans une bande de fréquences prédéterminée ; modulation d'une fréquence d'oscillation de l'oscillateur d'excitation (22) avec un décalage de fréquence de sorte que la puissance moyenne soit inférieure à la valeur maximale dans la bande de fréquences prédéterminée ; détermination d'une bande passante (B) d'un récepteur radio et modulation de la fréquence d'oscillation (fT) avec une fréquence de modulation (fM) qui est supérieure à la bande passante du récepteur radio.
