    Diagram Flip flop
AI Thread Summary
In drawing a timing diagram for a JK flip-flop, it is generally sufficient to show only the Q output unless the Q bar output is specifically required for the assignment. The Q bar output can be referred to simply as Q bar, indicating NOT Q. It is important to include all inputs in the diagram to ensure they are properly driven. Typically, outputs that are not used later in the logic do not need to be displayed. Clarity in terminology is essential, as homonyms can lead to confusion.

for j k flip flop,there is a inverse clock,Q(output) , Q bar(knot) output ,J and K
when drawing the timing diagram,is it necessary to state the output of the Q bar (knot) or only the Q (output) is enough??


pls help

that depends on your assignment requirement.

just a clarification.. You may state the negation of Q as just Q bar .. We understand it to mean NOT Q .. Your spelling knot is a homonym. It sounds like NOT but has a different meaning.
 
You would generally only show Q- in your timing diagram if you were going to use it for something later in the logic. You wouldn't usually show outputs that are unused. You do need to show all inputs, however, since you need to be sure to drive them with something.
