Learners compare animations of analog and digital data signals. A short quiz completes the activity.
By Terry Bartelt
In this learning activity you'll determine the voltages that can be topped off of a multi-resistor voltage divider that has one main power source.
Overflow and Underflow for Signed Binary Numbers
By John Casey, Terry Bartelt, Terry Fleischman
Learners examine the occurrence of overflow and underflow conditions in a programmable logic controller. It is recommended that users view the learning object “Signed Binary Numbers” in advance of this object.
The Transfer Function and Frequency Response of a Low Pass Filter
By Patrick Hoppe
Students learn how to predict how circuits will respond to varying frequency. They solve for the magnitude and phase angles.
Total Resistance in a Parallel Circuit
The learner will apply the three formulas used to find the total resistance of three types of parallel resistor circuit configurations.
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.
The Internet & Net Geners
Digital Divide - Internet and Net Geners of the Net generation.
Basic Internet concepts for kids
Radio Frequency Propagation
You'll focus on how radio frequencies spread under different circumstances.
