In this learning activity you'll identify the voltage levels produced or recognized by digital logic devices as valid or invalid logic state signals.

In this animated activity, learners examine the fundamental operation of a logic probe that is used to detect logic signals in a digital circuit.

Learners follow steps to trace logic signals from the inputs of several interconnecting logic gates to one output.

Learners will identify ladder logic diagrams and the logic functions they perform.

Students read information about basic logic gates including the gates' names, symbols, Boolean expressions, pronunciations, and truth tables. They then complete a matching exercise.

The schematic symbols of logic gates used in digital circuits are shown.

Students view the layout and operation of a digital logic probe.

In this animated object, learners follow a process for troubleshooting digital integrated circuits on a printed circuit board using a logic probe.

This interactive object is designed to help learners memorize the schematic symbols used in ladder logic diagrams. Learners quiz themselves using electronic flashcards.

Learners examine eight different kinds of faulty logic or perception that interfere with critical thinking. They are superstition, ignorance, clustering illusion, false analogies, gambler’s fallacy, irrelevant comparisons, post hoc fallacy, and slippery slope fallacy. In an interactive exercise, learners identify ways to overcome these barriers.

The learner will understand the operation of the six fundamental logic gates and the inverter by using truth tables, Boolean Algebra equations, switch analogies, and written statements.

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.

In this animated object, learners examine how to use a programmable logic controller as an alternative to hardwiring a ladder logic circuit.

In this learning activity you'll examine how logical addresses work. The IP address is the logical address assigned to a connection by the ISP or network administrator.

In this learning activity you'll understand what flow charts are and how they're used to create computer programs.

In this animated object, learners view the operation of an open-collector inverter with and without a pull-up resistor.

Learners view an animated demonstration of how to determine the final output of the combinational circuit.

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

Instructions on how to interpret state indicator symbols for input and output terminals of digital devices is presented.

In this learning activity you'll be introduced to the eight most common logical fallacies commonly used in persuasive speeches.
