  1. What Does 8 x 20-µs and 10 x 1000-µs Mean in Surge Testing …

    Apr 24, 2013 · I'm trying to understand the meaning of 8 x 20-µs and 10 x 1000-µs standardized transient impulses (or sometimes it's called a waveform). But what does it actually mean.

  2. What exactly are harmonics and how do they "appear"?

    May 21, 2012 · In case of a repeating waveform (like a square wave), when you do Fourier analysis you find that all the sines that compose the waveform have frequencies that are an …

  3. What is the difference between the terms wave, waveform, and …

    What is the difference between wave, waveform, and signal? Or do they have the same meaning? Can they be used in place of one another?

  4. DO-160 indirect lightning requirement confusion

    Oct 26, 2019 · For DO-160, there are Waveform 3, 4, 5A&B, and each waveform has its own requirement. Can some please give me an example on how to check if the tvs diode complies …

  5. Power Supply Lightning Protection - Waveform 5A in DO-160

    Oct 10, 2024 · The waveform 5A has a system impedance of 1 ohm. You will have to draw enough current to use this impedance to limit the voltage seen at the entrance to your power …
