(Flip-Flops) Identify the following statements as either true or false:

(a) The inputs to a level-sensitive latch always affect its outputs.


(b) Flip-flop delays from the change in the clock edge to the change in the output typically are shorter than flip-flop hold times, so shift registers can be constructed from cascaded flip-flops.


(c) Assuming zero setup and hold times, clocked latches and flip-flops produce the same outputs as long as the inputs do not change while the clock is asserted.


(d) A master–slave flip-flop behaves similarly to a clocked latch, except that its output can change only near the rising edge of the clock.


(e) An edge-triggered D flip-flop requires more internal gates than a similar device constructed from a J-K master–slave flip-flop.
