Question 1.
What is a latch?
Show hintHide hint
Think about how it holds a state.
Question 2.
Describe a D Flip-Flop.
Show hintHide hint
What signal is involved for the action?
3Question 3.
Which flip-flop toggles its state based on J and K inputs being high?
- D Flip-Flop
- JK Flip-Flop
- T Flip-Flop
Show hintHide hint
Think about the condition that produces toggling.
4Question 4.
True or False: An asynchronous counter requires all flip-flops to be clocked by the same signal.
- True
- False
Show hintHide hint
Consider how flips happen in timing.
Question 5.
Design a synchronous counter that counts from 0 to 15 and resets to 0. Describe the flip-flops used and how they connect.
Show hintHide hint
Think about how many bits are needed to represent the maximum count.
Question 6.
Create a truth table for a JK Flip-Flop and explain the output for every combination of J and K inputs.
Show hintHide hint
Recall the toggling behavior and the states before and after.
