Unit 9: Flip-Flops

Notes

Now, suppose we add a propagation-delay-based one-shot circuit to the enable line of this
D-type gated latch. Re-analyze the output of the circuit, given the same input conditions:

Comment on the differences between these two circuits’ responses, especially with reference
to the enabling input signal (B).
10. Shown here are two digital components: a D-type latch and a D-type flip-flop:

Other than the silly name, what distinguishes a “flip-flop” from a latch? How do the two
circuits differ in function?
