| description | L'invention concerne un procédé de commande d'un réseau (51, 53) de capacités ou de résistances commutables, connecté à un quartz (1), dans lequel la commande est effectuée par modulation de largeur d'impulsions.
A quartz crystal resonator is connected to an array of switchable capacitors or resistors. The switched actuation of elements of the array is controlled by bits of a control word. At least one of the bits of the control word is controlled by pulse width modulation to effectuate a tuning of the oscillation frequency of the quartz crystal resonator. |
