Learners consider why an impedance matching transformer is needed to connect an antenna to a television.

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

This learning object shows the symbols used to represent the type of pulse required at the clock input to activate flip-flops.

In this interactive object, learners examine standard and metric thread specifications used in engineering drawings. In a brief quiz, they identify various internal and external thread representations.

Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.

In this animated object, learners examine the formulas used to convert peak, RMS, average, and peak-to-peak AC voltages. A brief quiz completes the activity.
