Duty cycle, frequency and pulse width--an explanation 

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

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 ! 👍🏻🇬🇧❤️🍻👏🏻💪🏻😅😂

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

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

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

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

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

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

Brilliant and very well explained, thank you 😊

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.

Good and simple explanation , great teacher ,thanks Justin

Thank you and appreciate your effort. Greetings to you from Turkey .

Wow. Very clearly explained. Thanks Justin👍👍👍

AMAZING! Feel more prepared for my test tomorrow now

Great Tutor , Clearly Explained.Thank you !!

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

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

Very KNOWLEDGEABLE Very Helpful video thank you 👍👏 God bless you Justin Miller From Nick Ayivor from London England UK 🇬🇧

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!

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!

Many thanks for such a very simple explanation,

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

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

Nicely explained Mr. Justin Miller. Thank you

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

Thanks for posting this..very helpful.

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

This is a very well explanation. Thank you very much!!

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

Thanks so much for posting this incredibly helpful video!

Thank you! Very nice explanation.

Good video sir. Clear and easy to understand!

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

That explanation was poetry in motion!!! EXCELLENT!!!!

Best explanation I've seen thus far.

PRODIGY Justin Miller Thank you so much for sharing it 👍 Take care and have a great day PRODIGY Justin Miller From Nick Ayivor from London England UK 🇬🇧

Very very helpful. Appreciated thank you 🏴󠁧󠁢󠁥󠁮󠁧󠁿🙏

That made sense. Thank you Sir great video.

Thanks For Making this Clear to Me..:D

Thank you SO much. This was incredibly helpful

Thank you sir. Great explanation

you're a great teacher

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.

Great video, thank you!

thank you so much...this will be good automotive help with scanners

Excellent teacher, Thank you very much

Thank You Very much for your course it's very very useful ..

thank you, it really helped me

Awesome clarification!

Thank you for sharing it.

Very helpful. Thanks sooo much!

thank you , you make it easy to understand.

Thank you for this valuable information.

Seriously awesome video thank you!

Very good illustration .

thanks for such a simple explanition .

Excellent description

Very well explained.thank you.

great explanation! Way better than school does it!

Nice explanation! Thank you

Nice video, well done, thanks for sharing it with us :)

excellent video. Will there be a circuit for pulse generators for common rail injectors?

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!

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 ?

AWESOME VIDEO AND EXPLANATION!! 😎👍👍 IM FOLLOWING

amazing explanation, thank you so much

Great vid. Subbed. Thank you!

Good explanation!

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?

very good explanation, you just have been subscribed :D

Great Video!

excellent video

Good explain. Got it. Thank you.

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

Thank you so much for this video

Justin you are the best

Thanks for your efforts

GREAT EXPLANATION :)

Really great explanation great teacher thanks 💐🙏🙏💐💐💐💐💐💐💐💐💐💐

Thank you sir for explanation, this vedio make me to understand.

Well explained!

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.

Excellent. Thank you

Great explanation

sweet review

thx so much man really helped me

Thank for explaining time.

helpful! thanks!

thanks . very informative

Thank you!!!

Thank you. I was reading every definition of online and still couldn’t grasp the meaning of it at all. Seeing it visually helps understand it well. Also, if duty cycle of an output is 20% vs 50% that means the radio is poor quality and signals don’t get through far or well?

Like your way of Explanation justin

Thank you!

Nice job sir

Tks good vídeo.

It was awesome man

everytime i had of pulse width my mind went jumped to mm till now thanks

very helpful to a student

This was a plain and simple explanation. Any idea what would cause a DC fan that I’m attempting to drive via PWM to not spin at low duty cycles?
