![]() 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 ↓. ![]() After it reaches it's maximum value of 15 (calculated by 24-1), it resets to zero. For each clock tick, the 4-bit output increments by one. That’s why this configuration is called pulse-triggered JK Flip-Flop. 1 Copy 3 Views Open Circuit Social Share Circuit Description Circuit Graph This 4-bit digital counter is a sequential circuit that uses JK flipflops, AND gates, and a digital clock. So this circuit requires a complete pulse (0→1 →0) in order to change the output. 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. 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. As soon as the clock makes a rising edge ↑, which is a change from 0 to 1 (0→1), it triggers the master section.
