Duty cycle, frequency and pulse width--an explanation

These terms are often confused or used interchangeably, when they are actually three different ways of measuring an electrical signal.

[@J_Alrighty]

Thank you so much for this video. You managed to effortlessly simplify something I have struggled with for a long time.

[@smm8519]

Hello Justin, Thanks a lot for a useful session, your method in the explanation was amazing.

[@pleaseyourselfsir]

Justin Miller , thank you for taking the time and energy of making this highly educational video ! ... I wish I had seen this 8 months ago ! 👍🏻🇬🇧❤️🍻👏🏻💪🏻😅😂

[@AmmarLegato]

Much love and appreciation, many friends and TEACHERS tried to explain it to me, but none was as perfect as this ..

[@ishowhalal]

Thank you sir for taking your precious time to explain this lecture to us :)

[@waseemaq]

Great lecture. This is a great service to students learning these concept because these fundamental concept are often taught ambigously which leads to confusion. Thank you very much. Great work !!!. I was learning PWM and it was built on top of thses basics, specially Digital signal but nobody bother to emphasize what is Digital Signal and Analog signal. Cost me countless hours and agony until I stumbled on to this video lecture by Justin.

[@JeffMaigemu]

Thank you for this Justin! Simplest illustration I have come across so far

[@haylcron]

This was a huge help. Thanks so much for posting it!

[@ahmadalsenien590]

This is the best and fastest video explaining how they work. Thank you so much

[@jaykent6645]

Brilliant and very well explained, thank you 😊

[@issamqalajy5342]

Good and simple explanation , great teacher ,thanks Justin

[@DilshanMarasinghe]

AMAZING! Feel more prepared for my test tomorrow now

[@molajat1]

Wow. Very clearly explained. Thanks Justin👍👍👍

[@kylepetersen6520]

I really liked your simple explanation of sample and hold and an A-to-D converter. I think that was just enough information for people who don't understand it and don't wish to. though I think that stuff is cool, and I like going in-depth I know a lot of people don't and they really don't want to go in-depth about it.

I just came to know about pulse width modulation, but ended up learning much more, Thank you!

[@GaryParkin]

Thank you so much for your video. This is great stuff to know.

[@hopi9927]

Great Tutor , Clearly Explained.Thank you !!

[@MsRitchie225]

This was explained so well its really helped me make sense of lab scope automotive data. Thanks very much. As. Was struggling before.

[@ClaudinneV]

Thank you very much Justin. That was indeed very well explained :)

[@tonyrink9999]

Awesome video. I've watched a lot of videos where the instructor does a poor job of breaking this down, but you couldn't have made it easier to understand. Thanks!

[@JustinMillerAutomotive]

You're welcome! I'm glad it helped!

[@gordonyoud5975]

Many thanks for such a very simple explanation,

[@spy8464BB]

The teacher appears when the student is ready. Thank you !

[@robertbrandywine]

Yep, I just googled "What is the difference between duty cycle and pulse width modulation?" and arrived here.

[@juliosantos9289]

Good video sir. Clear and easy to understand!

[@gerrys6265]

Thanks for posting this..very helpful.

[@scottneels2628]

Thanks Justin, Great tutorial. Is there a way to copy an input digital 0-5v squarewave signal and output it exactly, with a variable delay? I've been trying to figure it out on Circuit JS1 using an rc delay but I lose the original signal frequency and amplitude. I've also tried a phase shift but I need it to be variable and can't figure out how to. I've even tried using a half bridge but was only able to recover the amplitude. I'm stuck.

[@edward_grabczewski]

Thanks. I was struggling a bit to remember what the terms meant when I was playing with a new multimeter!

[@feistent]

Thank you! Very nice explanation.

[@coryduncan6273]

Love the video. I'm trying to teach youngster in the about pulse width. Thank you.

thank you , you make it easy to understand.

[@Marthinusjacobus]

I brought several 220 volt, 50 cycle power tools from South Africa which I have been using here in California since 2004. How does the 60 cycles in the USA influence the operation of these tools? I have not notice anything untoward like a rise temperature etc. Thank you.

[@ravishankar1972]

That is very useful from chemist point of view. Thank you very much sir. Very very useful video for idiots guide or dummy guide to PWM ?

Hi Sir, how many PWM signals is required to control one BLDC motor, I am confused if I have a MC and then how to use the PWM to control the angle.

[@vaibhavprabhu04]

Justin you are the best

[@VahidBehravanVahid-Behravan]

HI There, Very good explanation and testing, thanx! can every PWM be set as positive offset frequency?

Nice! Could you say that an analog wave ist continuos and a digital discret? Thank you very much.

[@JustinMillerAutomotive]

Yes. That is correct.

[@TopLobster9975]

I’m trying to figure out the duty cycle of a thruster (space vehicle). I’ve got all kinds of values for the minimum pulse width, but not a specific time for a cycle. How do I figure that out?

[@helloworld8583]

I unsuccessfully struggled with finding some easy explanation of duty cycle on my native Ukrainian/Russian lng and i got fail. But your video so logical and pretty simple explain it. Thank you!

[@119vs155]

Excellent. Thank you

[@raviautoscanning]

Good explain. Got it. Thank you.

Thank you nice and knowledgeable video

[@RakeshYadav-tb2im]

thanks . very informative

[@havochari]

Well explained!

[@Ranjitkumar-tu9xf]

It was awesome man

[@nolimitsREAL]

ok, i understand how to calculate them, but what i don't understand: So the electrical signal is continous, in 25% on time, what happens with the rest ? what voltage goes to the output ? (0-5V) that it makes running with 25% .... It doesn't heat the pwm ?
