  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 integer multiple of the …

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

    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 with …

  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 supply.

  6. waveform - Triangular wave to sawtooth wave - Electrical Engineering ...

    Jan 7, 2021 · wanted to design a sweeper circuit to change a triangular wave into sawtooth wave. Is there a schematic for this to design a circuit?

  7. What does the US power supply waveform look like?

    Sep 6, 2016 · I know that we (typically) get 120 V AC in USA, but what does the waveform look like? Can anyone post a pic? How many phases are there, and what's the peak voltage?

  8. operational amplifier - Why does my op-amp circuit output a rectangle ...

    Apr 24, 2021 · If you want a non-inverting amplifier that outputs a waveform similar to the input, then you need to connect the feedback to give you a unity gain buffer. At the moment, it's connected as a …

  9. How to draw digital timing diagrams for documentation?

    Dec 3, 2019 · Well, it's really just Visio line segments and text boxes. Once you create the basic waveform types you want to use, it's easy to add them to a stencil or just keep copying them from …

  10. Sine wave shows up on oscilloscope but keeps moving

    Aug 28, 2020 · So I just press the "freeze" button, and then go for a cup of coffee, come back, and take my time, to leisurely zoom in or out, shift left or right on the frozen waveform to focus on the …
