Learners read how the NOR gate can be configured to obtain the other common logic gates. Schematics and Boolean expressions demonstrate how the AND, OR, and Hex Inverter functions are achieved through the use of only NOR gates
In this animated activity, learners examine how various NAND gate configurations and the logic signals produced throughout the circuit perform the functions of all of the other types of logic gates.
Students view schematics and truth tables that demonstrate how the AND, OR, and Hex Inverter functions are achieved through the use of only NAND gates.
The Operation of a Multiplexer/Demultiplexer Circuit
In this animated object, learners examine how a multiplexer and a demultiplexer work together when their data select lines are connected to the same binary counter.
The Multiplexer/Demultiplexer IC Data Transfer Circuit
In this animated activity, the learner examines how a 74150 IC multiplexer and a 74154 IC demultiplexer work together when their data select lines are connected to the same input devices.
Students read information about basic logic gates including the gates' names, symbols, Boolean expressions, pronunciations, and truth tables. They then complete a matching exercise.
In this animated activity, learners view the input and output leads of a JK flip-flop. They also see how it functions in each mode of operation. A brief quiz completes the learning object.
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.
Learners are introduced to the binary-coded decimal, a common way of encoding decimal digits in computing and electronic systems. A brief quiz completes the activity.
