Claims (1)
がスキューを生じて組合わされるものにおいて、該第２
の信号の立上り部と前記第１の信号の立上り部及び立下
り部により修正用信号が作られ、該修正用信号と前記第
１の信号の立下り部を論理演算して、前記第２の信号が
立上っている部分における前記第１の信号の所定の立下
り位置でのみ第３の信号が発生するよ・うに修正される
ことを特徴とする信号スキュー修正回路。In the case where a first signal with a short period and a second signal with a plurality of periods thereof are combined with a skew, the second signal
A correction signal is created by the rising edge of the signal and the rising edge and falling edge of the first signal, and the correction signal and the falling edge of the first signal are logically operated to generate the second signal. A signal skew correction circuit characterized in that the circuit is modified so that a third signal is generated only at a predetermined falling position of the first signal in a rising portion of the signal.
