Walk through the subscriber loop and learn how the signal travels from the central office to the subscriber.

Learners follow steps for reading a P&ID diagram of a closed-loop circuit.

In this animated object, learners examine the operation of a closed-loop system that maintains the speed of a conveyer belt as heavy boxes are placed or removed.

In this animated object, learners study the drawbacks of a single-loop armature of a DC motor and the advantages of a multi-loop armature.

Learners examine the factors that contribute to the delays in the response time throughout a closed-loop system.

Learners study an animated block diagram that describes the function of each element in a closed-loop system used in industrial automation.

The inverting amplifier configuration is presented. The closed loop voltage gain and the closed loop bandwidth formulas are explained, along with the concept of negative feedback.

In this learning activity you'll use the Spanning Tree Protocol to correctly set up a loop-free Ethernet local area network.

In this animated and interactive object, learners examine a heat exchanger as an example of an automated closed-loop system.

Students read about the characteristics of the ideal operational amplifier and compare them with the industry standard LM741C.

Students view the operation of a process controls system and examine the components and their function to prepare to work with the actual system.

In this animated object, learners examine a closed-loop feedback system that uses digital circuits to control the position of a gear rack.

Students are introduced to the non-inverting amplifier configuration. The formulas for closed loop gain and bandwidth are shown, and an example is given.
