In this animated activity, learners examine the construction of a binary counter using a JK flip-flop. The ability of the JK flip-flop to "toggle" Q is also viewed.

In this animated activity, learners view how to clear and preset a flip-flop to store a logic 0 or a logic 1.

In this animated activity, learners view the flip-flop and read about its outputs, the information it stores, and its storage conditions. A quiz completes the lesson.

In this animated object, learners examine the recommended procedure for troubleshooting a defective JK flip-flop using a logic pulser and probe.

This screencast shows the symbols used to represent the type of pulse required at the clock input to activate flip-flops.

Students examine the operation of synchronous and asynchronous inputs on a JK Flip-Flop.

The technique for designing a MOD 10 counter is introduced. Asynchronous inputs of a JK flip-flop are used to clear the counter.

The two types of digital devices, logic gates and flip-flops, and the types of basic operations they perform are presented.
