In this learning activity you'll explore the operation of a NAND gate using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.
Learners view the waveforms and voltages of an Edison Three-Wire System and read a description of the polarities across the secondary of the center-tap transformer. This transformer supplies power to residential homes.
In this animated learning object, students examine current, voltage, and the magnetic field strength of a series RL circuit while it is de-energizing during five time constants. A quiz completes the activity.
Transfer Functions: The RL High Pass Filter (Screencast)
Learners read how the RL high pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench and the resulting Bode plot is compared to the graph from Excel.
The Operation of a Multiplexer/Demultiplexer Circuit
In this animated object, learners examine how a multiplexer and a demultiplexer work together when their data select lines are connected to the same binary counter.
In this learning activity you'll review how an OR gate operates using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.
The TI-83 Plus Calculator: The Square Root Function
Learners follow step-by-step instructions for calculating the square root of a number using the TI-83 Plus scientific calculator. Steps for determining impedance are also shown.
