Definition of "JK Flip Flop" |
A style of flip flop that has a J input and a K input, and also may have a Set [S] and Reset [R] input. No change occurs when J and K are low. When the K is low the output is low and when the J is low the output goes high. When both J and K are high the output toggles. Truth Table to right. Examples ICs; 7473, 7476, 74107, 7470. |
Definition of "JK flip-flop" |
The JK flip-flop augments the behavior of the SR flip-flop ,J=Set, K=Reset by interpreting the S = R = 1 condition as a "flip" or toggle command. Specifically, the combination J = 1, K = 0 is a command to set the flip-flop the combination J = 0, K = 1 is a command to reset the flip-flop and the combination J = K = 1 is a command to toggle the flip-flop, that is, change its output to the logical complement of its current value. / Fiber optic refers to the medium and the technology associated with the transmission of information as light impulses along a glass or plastic wire or fiber. Fiber optic wire carries much more information than conventional copper wire and is far less subject to electromagnetic interference. Most telephone company long-distance lines are now fiber optic. / device that uses two inputs (J and K) to control the state of its Q and Q' outputs. A negative edge-sensitive clock input samples J and K and changes the outputs accordingly.The simplified truth |
