About This Chapter
Electrical Interference in Engineering - Chapter Summary
Electrical and electromagnetic interference affect many different electronic devices engineers develop. These lessons will explain different types of electromagnetic and radio interference. They will show how an electromagnetic pulse can damage sensitive electronics and different ways radios deal with frequency interference. When you have completed each lesson,you can test what you have learned with the interactive lesson quizzes. These lessons are designed with convenience in mind and can be taken on a wide variety of devices. Using these lessons, you will learn about:
- What an electromagnetic pulse (EMP) is
- How electromagnetic interference is created
- The different types of electromagnetic interference
- Why radio frequency interference occurs
- What co-channel interference is
- The formula used to figure the signal-to-noise ratio
1. What is an Electromagnetic Pulse (EMP)? - Definition & Effects
Science fiction movie writers love the idea. A huge EMP hits the earth and we're all suddenly back in the Dark Ages. In this lesson, we'll discuss the definition and effects of the electromagnetic pulse.
2. Signal-to-Noise (S/N) Ratio: Definition & Formula
Signal-to-noise ratio is the ratio of the strength of a signal to its background noise. In this lesson we'll become familiar with its formula and some of its applications, including in the context of climate change.
