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 ! 👍🏻🇬🇧❤️🍻👏🏻💪🏻😅😂

[@JeffMaigemu]

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

[@AmmarLegato]

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

[@ahmadalsenien590]

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

[@haylcron]

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

[@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.

[@jaykent6645]

Brilliant and very well explained, thank you 😊

[@ishowhalal]

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

[@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.

[@molajat1]

Wow. Very clearly explained. Thanks Justin👍👍👍

[@MsRitchie225]

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

[@issamqalajy5342]

Good and simple explanation , great teacher ,thanks Justin

[@AslamKhan-xt1vg]

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

Thanks a lot for you commitment to teach and knowledge.
God bless you.

[@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,

[@nickpierpoint4116]

Thank you so much for this video! so clear and easy to understand!

[@JustinMillerAutomotive]

Thank you.

[@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.

[@gerrys6265]

Thanks for posting this..very helpful.

Best explanation I've seen thus far.

[@JustinMillerAutomotive]

Thank you.

[@dennismolina2339]

great explanation! Way better than school does it!

[@anirudh3004]

Thanks For Making this Clear to Me..:D

[@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!

[@hagebootung]

That made sense. Thank you Sir great video.

[@bigsscore8378]

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!

[@VahidBehravanVahid-Behravan]

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

[@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.

hey, thanks,
whats the maximum frequency (effective) that is used? i saw as bissest as 500khz. why not 5mhz for example? what is behind this? thanks

great video.. just a note.. all the audio of this video is coming out of my left earphone.. not sure if it can corrected... thanks

[@ECOMMUSK]

sweet review

[@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?

[@mtyu8870]

Thank you!

[@scugglebottom]

Great video! Thank you for explaining it. Can you tell me for a given fuel flow rate and given direct injection pressure can the injection duration time change? And I guess if it can change, what can cause it to change?

[@JustinMillerAutomotive]

The duration is controlled by the ECU, which can control the pulse width (or amount of time) that the injector is commanded on. On many direct injectors, the injectors are actually commanded on multiple times during each event.

[@RakeshYadav-tb2im]

thanks . very informative

[@robertrobinson1454]

Thank you!!!

[@JohnFuller804]

helpful! thanks!

[@Ranjitkumar-tu9xf]

It was awesome man

[@sudhansumtripathy]

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.

[@umargul5644]

Great job thanks sir very useful thanks

[@ELECTROxigeno76.]

Tks good vídeo.
