Learners read how the transfer function for a RC 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 read how the transfer function for a RC low 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.

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.

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 how the transfer function for a RC low 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 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.

In this learning activity you'll create a packet filter.

In this animated object, students observe how the pulsating DC output voltage of a full-wave rectifier is filtered by a capacitor.

Studies show that more than 75 percent of all hydraulic system failures are a direct result of unclean oil. In this interactive object, learners examine the three primary types of hydraulic system filters. A brief quiz completes the activity.

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.

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.

The Ideal Bode plot is introduced. The three main topics covered are: corner frequencies, midband voltage gain, and the roll-off rate.

Learners examine a Filter-Regulator-Lubricator (FRL) unit that is used to prepare the air in a pneumatic system.

In this learning activity you'll examine a stateful packet inspection firewall that keeps track of legitimate Internet service requests, also known as dynamic packet filtering.
