Students read how the transfer function is developed for an RC low-pass filter. A straight line Bode plot is drawn through close approximations.

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.

Students learn how to predict how circuits will respond to varying frequency. They solve for the magnitude and phase angles.

In this interactive and animated object, learners follow instructions for finding the lowest common denominator for a group of algebraic fractions. Immediate feedback is provided. This activity has audio content.

Learners follow steps to establish the lower and upper limits in a spreadsheet.

Students follow step-by-step directions for entering data into a spreadsheet and reporting the results.

Instructions on how to interpret state indicator symbols for input and output terminals of digital devices is presented.

In this screencast, learners examine the function and location of the motor neurons and the damage that can result when they are injured.

In this learning activity you'll identify the voltage levels produced or recognized by digital logic devices as valid or invalid logic state signals.

Introduces two methods of determining bend allowance; one is simple and is an approximate, the other is more precise. Interactive part has learner calculate bend allowance and blank size.

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.

In this learning activity you'll examine how a data file is broken into packets and transmitted over the Internet.

In this learning activity you'll use Maslow's Hierarchy and choose which need is taking precedence and which is being sacrificed in each situation.

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 interactive object, the learner reads an explanation of how various shielding gases are used in GMAW and FCAW. An exercise completes the activity.

This project gives a drawing with steps to complete the activity.

The learner will understand the importance of following instructions.

In this interactive and animated object, learners examine the flow of electron current into and out of hot and neutral sockets during each alternation of an AC waveform. A brief quiz completes the activity.
