In this learning activity, learners will learn to calculate the average voltage produced by half-wave and full-wave rectifiers.

In this video, we’ll go over the necessary steps to square the toolhead on a Bridgeport mill.

Students read an explanation of the operation of an operational amplifier that functions as a comparator.

Students read about the characteristics of the ideal operational amplifier and compare them with the industry standard LM741C.

Students read about the ideal versions of the four common filters (low-pass, high-pass, bandpass, and notch), and view graphical representations of the filters' frequency characteristics.

Learners view the operation of the 7485 integrated circuit magnitude comparator in this animated object. A quiz completes the activity.

In this animated object, learners examine the operation of a multiplexer and the function of the data input and selector lines. A brief quiz completes the activity.

In this animated object, learners examine the operation of a demultiplexer along with the data output and select lines. A brief quiz completes the activity.

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.
