The schematic symbols of logic gates used in digital circuits are shown.
Drill Press Parts
By Kelly Curran
In this learning activity you'll explore parts of the drill press.
The 7493 IC Binary Counter (Screencast)
By Terry Bartelt
In this screencast, learners examine the construction of a 7493 IC as mod-2 and mod-8 up-counters. They view how this binary counter can be modified to operate at different modulus counts.
Voltage Sources in Parallel
The effect of connecting voltage sources in parallel to increase amperage to a load is presented.
Lathes: Turning Stainless Steel
This document is a visual and text description of turning stainless steel on a lathe.
Schematic Diagram Symbols
In this learning activity you'll review various types of common components used in electronics and view their schematic diagram symbols.
Electrical Switches & Pushbuttons
In this learning activity you'll review the operation and schematic symbols of various types of switches and push buttons used for electronic circuits.
Assembling a Circuit from a Schematic Diagram
In this animated object, students examine the steps for wiring an electrical circuit from reading a schematic diagram.
In this learning activity you'll describe the operation of an AND gate by using a truth table, a waveform diagram, a Boolean Algebra equation, a switch analogy, and a written definition.
Logic State Signals
In this learning activity you'll identify the voltage levels produced or recognized by digital logic devices as valid or invalid logic state signals.
Nondestructive Examination Symbols
You'll learn to identify nondestructive examination abbreviations and they use in examination symbols.
You'll focus on terminology related to designing a hypothetical program.
