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

Explore how to prevent injuries caused by falling from ladders or elevated heights by looking at the parts of a ladder, ladder safety rules, and personal fall protection systems.

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

In this animated object, learners study the operation of a ladder circuit that controls the rotational direction of a DC motor.

Learners study the operation of a ladder circuit in which coils on one rung control contacts in other rungs.

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

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

The explanation and use of timing diagrams used in digital electronics to graphically show the operation of various circuits are given.

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