IPC: G06F11/34
Filed: 1988-06-20
Abstract: PURPOSE:To freely change the number of pulses produced in a unit time by counting the number of pulses in a prescribed unit time of a pulse generation means to compare the pulse number with the prescribed number of outputs of a pulse number setting means, stopping the pulse output when the coincidence is obtained by comparison, and restarting the counting jobs at the unit time. CONSTITUTION:The basic pulse of the output of a basic pulse generation means 4 is applied to a pulse output circuit 5 and the output of this circuit 5 is branched and added to a counter 6. The output of a unit time detecting circuit 9 is also added to the counter 6. Then the output of the counter 6 is added to a comparator 8 and compared with the output of a output pulse number setting circuit 7. If no coincidence is obtained between both outputs, the output of pulses is continued through the circuit 5. While the output of pulses is discontinued when the coincidence is obtained between both outputs. Thus the counter 6 stops its counting action and the comparison result is also held for the output of the comparator 8. When the unit time passes, the circuit 9 outputs a pulse showing the lapse of the unit time. Then the counter 6 is initialized and the output of pulses is restarted.
