  • Method and circuit for retuning the frequency of a frequency source
    Patent number: 5070517
    Abstract: In order to adjust the frequency of an oscillator in a substation of a network to a reference frequency of the network, a reference station is provided with a high precision oscillator which is connected to a clock input of a counter. If this counter has a defined counting state, a start signal is generated and transmitted to said substation. At another defined counting state a stop signal is generated and transmitted to said substation. In the substation the oscillator to be adjusted is connected to a local counter, which counts the pulses of the oscillator between said start and stop signals. The count of this counter then is used as a measure for the frequency deviation of the oscillator and can be used for generating a control signal to adjust the frequency of the oscillator of the substation.
