Abstract
PURPOSE:To reduce both the discontinuity of the detection pulse due to drop-off of the input pulse and the error detection due to the noise, by providing the RAM or the like which stores the pulse arrival hysteresis with every pulse train. CONSTITUTION:RAM9 is provided to store the hysteresis of the arrival pulses before a fixed time, and the interval of the pulse train to be detected is preset to sequential address counter 8 via control data 7 of the computer of the like. Thus the timing with which RAM9 is referred to or renewed is set. If arrival pulse A exists at input terminal 1 at the time point when read/write circuit 10 reads out the contents of RAM9 in the corresponding address and the contents are set to shift register 12, the bit of the 0-power digit of 2 in register 12 is turned on through timing circuit 11 with shifting of the contents and then turned off if no pulse A exists with the contents shifted respectively. The renewed contents of register 12 are written 10 again into RAM9. The informtion stored in RAM9 is the hysteresis of pulse A before a fixed time.
