Flip-Flop Timing Parameters and Circuit Behavior AnalysisQuestion 1Which of the following flip-flop timing parameters indicates the time it takes a Q output to respond to aninput?Question 1 options:tw(1), tw(h)fmaxts, thtphl, tplhSaveQuestion 2Asynchronous flip-flop preset and clear inputs generally:Question 2 options:cause the outputs to change states depending on the SR, JK, or similar controllinginputs.cause the outputs to change states as soon as theinput clock makes the desiredtransition.clear the inputs so the flip-flop can start over.act as manual overrides that cause the outputs to change states regardless of theinputs or clock transitions.SaveQuestion 3Thesetup timeof aclocked flip-flop is:Question 3 options:the maximum amount of time that an output must remain stable after an activeclock transition.the minimum amount of time that an output must remain stable before an activeclock transition.theminimum amount of time that an input must remain stable before an activeclock transition.the minimum amount of time that an input must remain stable after an active clocktransition.SaveQuestion 4The symbol for a flip flop has a small triangle-and no bubble-on its clock (CLK) input. The triangleindicates:Question 4 options:the FF is level active and can only change states when the CLOCK = 1.
