PURPOSE:To simplify the constitution of hardware by obtaining a control signal by controlling the counting operation of a counter by the output of a flip-flop (FF) and by decoding the counter output. CONSTITUTION:When a set signal is applied to an FF1 and FF1 is set, a gate 3 is opened to apply a clock pulse from a reference clock generator to a counter 4. The count contents of the counter 4 are applied to a decoder circuit 5 to obtain desired control signals from terminals 0'15 successively. When the FF1 is reset, the control signals are ceased. This is effective when a controlled system is controlled cyclically. |
