Abstract
PURPOSE: To simplify circuit constitution and to facilitate the measurement of a time, by detecting pulse input by either one of input channels and successively storing the count value at that time and the data relating to the detected number of channels in an FIFO and subsequently reading the same in succession by a processor to operate the timewise relation between an input pulse cycle and each of the channels.
CONSTITUTION: The pulse input signals of (n)-channels are latched on the basis of the clock from a clock generator 3 by the data latches 1 of a time measuring circuit and the rising or falling of the outputs from (n)-stages of the latches 1 is detected by edge detectors 2. The output data detected by the detectors 2 are stored in an FIFO memory 7 as channel data and the counter data obtained by counting the clocks from a counter 4 are stored in an FIFO memory 8. The channel data and counter value from the memories 7, 8 are read to be applied to a processor 10 and the desired timewise relation relating to input pulses is calculated.
