if Q = 1, the lower NAND gate is enabled and the flip flop will be reset hence Q will be 0. In other words, when J and K are both high, the clock pulses cause the JK flip-flop to toggle. The truth table for
the input which is passed will always change the state of the output.Thus the truth table for the J-K flip-flop is the same as the truth table in Fig.4.19,except that we indicate a change of output state for the hitherto forbidden input state.The J-K Flip-Flop thus gives us,in ...

j-K型钾触发器。另一个问题是基本的r - s触发器是禁止国家在投入。这可以消除安定的投入与产出的触发器,从而阻碍之一投入所示fig.4.23 。加上盖茨这里有抑制1输入门的输出是1 。有-走在前列的,投入是通过永远改变状态输出。因此真值表为歼钾触发器是相同的真值表在fig.4.19 ,除了表明我们改...
