Voltage is not Duty Cycle X Voltage. This is the way: duty cycle of a rectangular waveform, which represents the ratio of the pulse duration to the total period, affects the RMS value. For a rectangular waveform with a certain duty cycle, the RMS value can be calculated using the formula: Vrms = Vpeak X square root of duty cycle Where Vpeak is the peak amplitude of the rectangular waveform. As the duty cycle increases, meaning the waveform spends more time at its peak amplitude, the RMS value also increases. Conversely, as the duty cycle decreases, the RMS value decreases because the waveform spends less time at its peak amplitude.
You could bias the ground. You can raise the voltage on the ground pin to whatever device your trying to use the pwm signal on. If you make it exactly half the max voltage, you will effectively have your -1 and +1. Just make sure your device is isolated from any other grounds. Unless you really understand what your doing, keep everything battery powered and don't use wall power adapters as that ground could cause a short circuit.
Hello, I'm a physics grad student, so I needed more info on PWM to make a sound modulated Tesla coil. Like how to turn analog signal to PWM. But everything you've said in the video was explained very well, and it helped. I hope you don't take it the wrong way...
Mia P I'm in 9th grade and learning basic electronics. This video really helped me understand the concept of PWM. I believe this video was targeted for people more like me, not a physics grad student.
A good explanation of the morse-signs history which results to the computer, Thanks.
Good teacher
Awesomely clear and on point!
Please make more videos. I loved the explanation!!!

Very interesting explanation, appreciate your effort and thanks a lot
best teacher.
Learned division very well.
a very perfect explaination
Good explanation
Woww Tat was a perfect demonstration :)
informative videos
Thanks...but waiting for more such videos
Great video overall pwm, I watched
Very clear, concise and complete! Thank you!
Nice work
Beautiful 🥰
Good work
Beautiful 😍
Vielen dank!
Beautiful ❤️❤️❤️
Very nice 👌👍
Beautiful
Excellent thanks
nice perfect explanation
Beautiful 🏆🏆🏆🏆🏆
Good job
Thanks a lot,
good explanation.
Thank you :)
is it possible if pulse don't keep the same value for example x0=4V,x1=0V,x2=1V and x3=2V .how to draw the pWM signal
Gracias!
Por nada!

You're welcome.
nice lecture
superb
good job!!
Amazing
Thank you man.
thx sir finnaly i got concept
Good video.
halim
good explanation very simple...
very nice
It's amazing
thanks!
great...thanks
Execllent
I am using atmel 89c52...how to use in pwm?...
nice🥰🥰
How can I invert the polarity instead of having an OFF cicle. What I mean is, in one period I need +1 cycle and -1cycle.
Thank you

Great
Nice
What does synchronous PWM mean?
What are the consequences of not having does synchronous PWM
Good
thank you
nice thank you so much
Ty sir
good experience
good
nice
explication good
sir 1v is how will be came
شكرا اخي

I thought it would go into more details :/ This is more of an explanation for a primary school kid.. But thank you.
Hi! Thanks for the comment! What more information where you looking for? I'm going to start up this channel and would appreciate your view.

Please Pwm ac or dc current??
PWM is a DC current because it has the same direction all the time. But you can say it is a pulsing and DC current.
Wow
굿
wow
the title should be duty cycle not PWM
ncc
Makes my mega hurt.
why is 1/5 * 100 = 20%?
It should'v been 100%. Not just 100
You can use your calculator if you have one 100/50 = 0.2 x 100 = 20%
Beautiful 🥰
