and can be used to store state information. The state can be changed by applying one or more control inputs and will have one or two outputs. It is the basic storage element in the digital circuit diagram. The logic circuit designer will have SR, D, JK, and T flip-flops for ...
A logic JK flip-flop structure is disclosed which may have a dynamic, semi-dynamic or static behavior as far as the clock signal is concerned. The structure of the invention is particularly simple in design and has a minimum number of transistors although it is insensitive to parasitic noise ...
Starting from the excitation table for the JK Flip-flop, this paper introduces the logic design of synchronous sequential circuit and asynchronous sequential circuit based on single-edge-triggered JK flip-flop, and proposes the complete state equation. Besides, it discusses the logic design of asynch...
