Abstract

PURPOSE:To correct the pulse fall-out and then realize the counting of the correct pulse number, by deciding the count-up of the counter in the fixed timing and through the scanning of the input signals. CONSTITUTION:Sequence signals A-E within one scanning are generated to carry out control 1 within each sequential scanning, the input signal sampled by signal A within one scanning is stored in FF5. And the output of FF5 is set to FF6 via signal E, and then comparison 7 is given between FF5 and 6 to obtain outputs OUT1 and 2. Counter 3 is operated in sequence by OUT1 and signal D, and the count output is compared at 8 with the set value. Then counter 3 is counted up by one by the non-zero output of counter 3, OUT2 and signal B each. And counter 2 is counted up by one and two with signals B and C and signal B only in case the comparison result of the counting is smaller and larger than the set value respectively.
