An activeHIGH input SR latch has a 1 on the S input and a 0
An active-HIGH input S-R latch has a 1 on the S input and a 0 on the R input. What state is the latch in? Q= 1, Q = 0 Q = 0, Q = 1 Q = 1, Q = 1 Q = 0, Q = 0 Which symbol is used to identify edge-triggered flip-flops? The letter E on the Enable input. An inverted \"L\" on the output. A bubble on the Clock input. A triangle on the Clock input. Refer to Figure 8-8. What value should \'X\' represent in the state table? 1 0
Solution
The answers are
Q 18:active high inputs and set input is 1 then the abswer is option A
Q19: option D
Q20: the answer is 1
I.e. truth table shows 111 state is equal to next state 11x.
