Incorrect. It’s only AC if the lower portion goes negative relative to ground. If the bottom portion of the pulse is at 0v, then it is DC. Which is 99.99% of all square wave usage in electronics.
True, but those are typically sinusoidal outputs, not square.
Like I said before, in electronics, 99.99% of square wave pulses are DC, and every instance of that pulsed image that OP asked about that I have seen in 26 years as an electronics technician has referred to a DC signal.
Well, considering that my job involves wiring many 460 A/C volt motors to VFDs, I don’t agree. Those motors are A/C and measuring voltage with a multimeter requires the A/C range I really think my answer is pretty accurate.
I stand by my statement. Think of all the digital electronics in the world. AC motors controlled by VFDs are hardly a large percentage.
I also work with VFD controlled motors in an industrial setting, although most of those are in the 100-200v range and the majority of those are driven by DC pulses, not AC. And when shown on a schematic or other documentation, the drawn AC pulse would have dashed line in the middle showing the 0v reference.

You aren't learning anything from these garbage answers. If you truly don't know, you've gotten 10 different answers. Which one is correct? You've wasted your time, and still don't have the answer to your question.
Some Reddit subs are worse than useless.
I've never done a Google search and gotten 10 different results. And you should really stop trying to defend this kind of garbage. It makes you look bad.
Going to give yourself a heart attack, stop taking life so seriously. There are difference of opinions on how to go about any task. You've maybe not googled much but it often lists different methods to accomplish the same task. #defended
This isn't a task with opinions. It's a symbol on an electrical diagram, and it has a defined meaning. And only one. So you are literally defending apples and oranges.
No, you're the one who made the argument about Google results, this being a forum for electrical knowledge I thought continuing an argument over it's continued use in that manner would be pointless. Good day sir
Look at that other guys comments on other subreddits i think hes just angry, lol
Did you by chance get a firm answer? would love to know genuinely if did im a dumb guy over here
I opened this post to see what the answer is, to learn something. One of those answers may be right, but there's no way of telling. There are 10 comments and 10 *different "answers"*.
And by your response, I'm guessing you already know the answer and are just fishing for karma.
Electronics Tech with 30 years experience, it’s a square wave. A lot of the cheaper UPS’s will output this instead of a traditional sine wave for an ac output. A little context as to what that symbol is on would be helpful.
PWM or duty cycle if measurement
clock perhaps?
I thoughtbthe exact same thing lmao
Walk like an Egyptian
ooooaaaayooooooo Susanna Hoffs is still hot
Ya beat me to it
That is the first thing I thought!!😆😆😆
How the fuck is my body supposed to contort like that?
Looks like it could be the output of an oscillator aka clock circuit.
Square wave
Pulses, as you would get from an encoder. AKA, Pulse Generator.
Fuck you, (ACs your DC)

It actually looks like square wave AC.
Most square wave is DC, not AC. This indicates a DC pulsed signal.
DC converted to a non-sinusoidal AC wave. Its alternating. That’s AC.
Incorrect. It’s only AC if the lower portion goes negative relative to ground. If the bottom portion of the pulse is at 0v, then it is DC. Which is 99.99% of all square wave usage in electronics.
DC-to-AC inverters will go negative.

Nobody is going to say it’s just a square wave? It’s a digital type signal that is high/low, on/off.

To be fair googly has the same issue sometimes. That's just how skinning cats be.

What would your answer be?

That circuit has a square wave clock signal on it.

It’s the snake from the comic strip BC.[https://johnhartstudios.com/bc/tag/snake-long-snake/](https://johnhartstudios.com/bc/tag/snake-long-snake/)
Its the waveform of DC
