PURPOSE:To take synchronization of two counters in a short time with simple constitution by detecting that an output of one counter and an output of the other counter are in a different logic state and controlling the one counter with a pattern detection means generating a pulse. CONSTITUTION:A pattern detection means 3 having two counters 1, 2 supplying a same clock CLK and outputting a same waveform pulse and detecting that an output of the one counter 2 and an output of the other counter 1 are in different logic state and generating a pulse is provided on the count circuit and the generated pulse controls the counter 2. Thus, the two counters 1, 2 are synchronized in a short time 1, 2 and the counter circuit with small circuit scale is realized. |
