Abstract :
Recent improvements in precision time-interval counting techniques are presented. Real-time autocalibration using an adaptive method for setting the optimum calibration rate, robust estimation of counter parameters, and input data filtering are discussed. The techniques described were evaluated during the development of time-interval counter T-1810B for satellite LRS in the Polish Academy of Sciences. Two adaptive calibration algorithms were tested, and results are presented
