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

Learners examine animations of the most common transmission signals used in automated systems, such as 4 mA to 20 mA, 3 psi to 15 psi, and 0 to 10 volts. A brief quiz completes the activity.

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

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

In this animated object, learners examine the signals produced at the N.O. (normally open) and N.C. (normally closed) outputs of sourcing and sinking four-wire sensors. A brief quiz completes the activity.

In this animated activity, learners examine how an electronic converter changes digital signals to analog signals. Sections of a synthesizer are identified, and the operation of a D/A converter is demonstrated.

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

The learner will recognize common gestures and identify the meanings associated with those gestures.

Learners view animations showing how electrical signals are applied to the coils of a stepper motor to perform microstepping. A short quiz completes the activity.

In this animated object, learners examine the signals produced by sourcing and sinking two-wire sensors. A brief quiz completes the activity.

In this learning activity you'll examine how electronic converters convert between analog voltages and proportional digital signals.

In this animated object, learners examine how magnetic waves are transmitted as radio signals.

In this learning activity you'll follow the process of converting digital data into a series of analog signals.

The learner will be able to represent steady-state AC sinusoidal signals using phase vectors, which will lead to a simplified technique of analyzing AC circuits in a very similar way that we analyze DC circuits.
