A device and method provide for an accurate output from a unit, such as an oscillator and/or clock providing an output indicative of frequency and/or time. The device includes a processing section having a microprocessor that develops a model characterizing the performance of the device, including establishing predicted accuracy variations, and the model is then used to correct the unit output. An external reference is used to provide a reference input for updating the model, including updating of predicted variations of the unit, by comparison of the re...
A method for enhancing accuracy of an output of a unit utilized with a utilization network, the output of the unit having an accuracy which departs over time from a predetermined standard, said method comprising: receiving the output of the unit; establishing predicted variations of the output of the unit due to random deviations and systematic time offsets and based upon a comparison of said output of said unit with a reference input indicative of the predetermined standard; utilizing said predicted variations to modify the received output of the unit t...
