Abstract

Abstract A method for measuring time intervals, by which the time interval of interest is coarsely measured by comparing it with a reference scale formed from a serves of precisely timed pulses, a fine measurement is then made of its parts contained between the pulses bounding the measured interval and the timed pulses, after which the coarse count is altered according to fine count, the fine count, the fine measurement being taken of the parts of the time interval contained between the pulses bounding it and those timed pulses the time interval between which is a multiple of the number of timed pulses at least equal to the number of possible different coarse counts of the same time interval. A method for measuring time intervals, by which the time interval of interest is coarsely measured by comparing it with a reference scale formed from a series of precisely timed pulses, and a fine measurement is made of its parts contained between the pulses bounding the measured interval and the timed pulses, after which the coarse count is altered according to the fine count, the fine count being changed by as many units of coarse measurement as will correspond to the change of the time interval between the timed pulses to which fine measurement is made of the carry from the previous measurement, as it is completed to a multiple of the number of timed pulses at least equal to the number of possible different coarse counts of the same time interval, and this adjusted fine count is taken as that fine count which is used as a basis for the adjustment of the coarse count. A device to realize the former method, comprising a time converter one output of which is connected to the input of a coarse-count readout means and the other output to the input of a fine-count readout means, characterized in that it comprises a coarse-count correcting means the inputs of which are connected to the outputs of the coarse- and fine-count readout means, respectively, and the output is connected to the input of the coarse-count readout means, while an apparatus realize the latter method additionally contains at least one fine-count correcting means whose input is connected to the output of the time converter and whose output to the input of the fine-count readout means.
