Aproach to the logic of different types of Flip-Flops and their usage in the implementation of counters
Un acercamiento a la lógica que siguen los diferentes tipos de Flip-Flops y su utilización en la implementación de contadores
A J-K flip-flop is nothing more than an S-R flip-flop with an added layer of feedback. This feedback selectively enables one of the two set/reset inputs so that they cannot both carry an active signal to the multivibrator circuit, thus eliminating the invalid condition.

JK Flip-Flop implementation with help of D Flip-Flop (dealing with delay). As I can say, - the first one working JK version on CircuitVerse)))
