The JK Flip Flop ( Digital Electronics, Derek Molloy)

This video lecture, tutorial describes the JK FlipFlop in detail. I begin by describing the general operation of a 7473 JK flipflop, showing the toggle state that makes this flipflop important for many applications. Then I show in detail how we can create a JK flipflop using NAND gates, describing both edgetriggered and pulsetriggered configurations. I implement both types of circuit, using a pulse generator for the edgetriggered version and a masterslave JK flipflop for the pulsetriggered implementation. Finally, I show how we can add asynchronous set and reset inputs for the masterslave configuration and implement a circuit to demonstrate that this works correctly. This video is part of a module on Digital Analogue electronics that is taking place at Dublin City University, Ireland.
