In this learning activity you'll practice converting between hexadecimal and decimal and between hexadecimal and binary numbers.

Learners examine the Karnaugh map for a three-variable system. Several examples are given.

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

In this learning activity you'll review the hexadecimal numbering system.

Students analyze the eight single variable Boolean theorems and their expressions.

Learners examine how to multiply the gate propagation delay by the gate power dissipation to find the speed-power product. Examples are shown.

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.

In this animated activity, learners examine how an electronic converter changes digital signals to analog signals. Sections of a synthesizer are identified, and the operation of a D/A converter is demonstrated.

In this animated object, learners examine the operation of a multiplexer and the function of the data input and selector lines. A brief quiz completes the activity.

In this learning activity you'll practice using the 4-input truth table.

Learners read how to calculate the MOD number and how it is used.
