Sequential circuits are different from combinational logic because_(?)_. no feed

Question

Sequential circuits are different from combinational logic because_(?)_. no feedback paths occurs with sequential logic. inputs are used but no outputs are developed. sequential circuit have inputs, outputs and internal states (from a prior time). sequential logic allows a single gate to output 4 conditions O,I,J,K In Figure 1a:Assume R = 0. What happen* to the latch if S goes from 0 to 1? (*Explain what happens to Q.) Continuing with question 2: S is at 1. now it goes back to 0, what happens* to the latch? (*Explain what happens to Q.) In Figure 1a: Assume S = 0. What happens* to the latch if R goes from 0 to 1? (Explain what happens to Q.) Continuing with question 4: Ris at 1, now il goes back to 0, what happens* to the latch? (*Explain what happens to Q.) What is the meaning of the "bubble''in the S and the R line of Figure 1b? (Explain it in terms of what the input signal must now be like for a Set or Reset to happen.) In Figure 1c, what does the 'En' input do? (Explain what happens when it is high and when it is low. In Figure 1c, what happens to Q when D = 0? (Assume En is high) In Figure 1c, what happens to Q when D = 1? (Assume En is high) An edge-triggered flip-flop is one that _(?)_. consists of a master-slave pair of latches. outputs a new value at Q only on the transition of the clock (....not ils level). can be built in both positive and negative edge triggered styles. all of the above are true

Explanation / Answer

1.c

2. Q becomes 1

3.it remembers. So, Q=1

4.Q becomes 0

5.it remembers. So, Q=0
