Telemetrie-Periodendauer-Messverfahren.

A telemetry period of length measuring process achieves an increased measuring resolution by first counting timing pulses over a period length of the measurement signal to detect an approximate period length by then reading out a table containing the period length counter status in order to obtain a measuring period quantity assigned to a period length range, whereby the quantity of measuring periods is selected so that counting the timing pulses by means of a counter does not cause a counter overflow even in the event of the longest period length of said period length range, this being followed by counting the timing pulses over the period length quantity of measuring signal periods, so that finally, the counter status thus obtained can be transmitted together with a coding of the measuring period quantity to a telemetry receiver.
