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.

Transfer Functions: The RC High Pass Filter with Bode Plot
Students view the development of the transfer function for a RC high pass filter. They also read how a Bode plot is developed through simple approximation techniques for both the magnitude and phase.
Transfer Functions: The RL High Pass Filter With Bode Plot
Learners read how the transfer function for a 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.
Learners examine the circuitry in a DC variable speed drive that prevents the motor from running at 0 rpm or at maximum speed under certain conditions.
Students read about the ideal versions of the four common filters (low-pass, high-pass, bandpass, and notch), and view graphical representations of the filters' frequency characteristics.
Dietary Manager Training: Classifying Foods According to Nutrient Density
Students read about foods that are high in nutrients compared to the number of calories. They identify if certain foods have high or low nutrient density.
In this animated activity, learners study the principle behind an inductor producing a high momentary voltage while its magnetic field collapses. A short quiz concludes the lesson.
Learners view videos of law enforcement and corrections officers describing their jobs and the opportunities in their fields. Because this object contains large video files, it is best viewed using a high band width connection. Low band widths will result in longer download time and video delays.
