Learners compare animations of analog and digital data signals. A short quiz completes the activity.

Learners consider the factors that determine how well an inductive proximity sensor can detect an object. Those factors are size, position, and the material from which the target is made. A brief quiz completes the activity.

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

In this animated object, learners examine an analog closed-loop feedback system that uses potentiometers to control the position of a gear rack.

Learners use two calculations to prepare a graphical solution to the biasing of bipolar junction transistors and junction field effect transistors. This method eliminates the problem of having to re-calculate the operational Q point when dealing with hard saturation.

Students read about the common characteristics of the Junction Field Effect Transistor. They also explore the schematic symbols and the basic operation of the JFET.

The ohmic region of the E-MOSFET is identified. Formulas are given to determine the proper operation in the ohmic region. An example of circuit analysis is also given.
