Rotating Vector Representation of the Sine Function
The learner will be able to represent steady-state AC sinusoidal signals using phasors, which will lead to a simplified technique of analyzing AC circuits in a very similar way that we analyze DC circuits.
In this animated activity, learners examine how various NAND gate configurations and the logic signals produced throughout the circuit perform the functions of all of the other types of logic gates.
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 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.
Using the Microstepping Technique for Stepper Motors
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 teaching and learning aid, the user can alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
