Unlike the Master-Slave design, which needs a complete pulse, you can also build an edge-triggered design that triggers from a rising edge ↑ or a falling edge ↓. That’s why this configuration is called pulse-triggered JK Flip-Flop. So this circuit requires a complete pulse (0→1 →0) in order to change the output. But for the flip-flop to make any change, its Clock input must be 1. Once the clock signal produces a falling edge ↓, a change from 1 to 0 (1→0), it triggers the slave section, causing the Q output to reflect the master’s output value. The J and K inputs of the JK flip-flop can be used to set, reset, or toggle the output, like this: J1 and K0 sets the output to 1. Positive Clock, Active HIGH Set and Reset inputs type This type of JK Flip-Flop will function on the rising edge of the Clock signal. These signals are connected to the slave section, but this doesn’t trigger on the rising edge because the clock has been inverted. As a result, the value of the outputs in this section changes. The J-K flip flops must be in the toggle case for this purpose. As soon as the clock makes a rising edge ↑, which is a change from 0 to 1 (0→1), it triggers the master section.
