Learners compare animations of analog and digital data signals. A short quiz completes the activity.
Strength of Materials: The Centroid of a Quadrant
By Steve Whitmoyer
In this animated and interactive object, learners calculate the area and centroid of a quadrant.
The TI-83 Plus Calculator: Complex Conjugate Conversion
By Patrick Hoppe
Learners view the steps to find the complex conjugate of a number using the TI-83 Plus calculator. They are encouraged to work the examples given.
By Terry Bartelt
Learners view an animation showing how the volume of a given quantity of gas varies directly with its temperature.
The Transfer Function and Frequency Response of a Low Pass Filter
Students learn how to predict how circuits will respond to varying frequency. They solve for the magnitude and phase angles.
Capacitor/Inductor: An Auto Analogy
By Roger Brown
Learners compare the experience of driving an auto to the circuit responses of RL (resistance/inductance) circuits and RC (resistance/capacitance) circuits. Acceleration, position, speed, and torque are graphed.
Analog and Digital Converters
In this learning activity you'll examine how electronic converters convert between analog voltages and proportional digital signals.
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.
Analog Ohmmeter Operation
Learners follow procedures for measuring resistance using an analog ohmmeter. They examine the use of the Function Switch and the Range Switch and practice reading a non-linear scale. A brief quiz completes the activity.
Analog Ammeter Operation
Students examine the procedure to measure current with an analog ammeter. The use of Function and Range switches is explored along with reading the needle position on the meter scale. A brief quiz completes the activity.
