Thank you sincerely for the explicit tutorials which you make very easy to understand. Sharing your concise explanations and knowledge is immensely beneficial to persons who have the passion to study electroncs but are unable to afford courses. It is also noteworthy of your service to mankind.
One of the few guys that explain the WHY's of Everything ! "Comparator Senses the analog world, and gives it to the digital world" That's WHY they are interfaced on my PIC microprocessors ... It makes Sense.
Even though he's a native english speaker, his pronounciation of comparator seems a bit off, as observed in other comments. Thank You for the excellent presentation, mr. Loflin!
I did an experiment using two comparators to see if I could get a DC motor to behave like a servo. I connected a control-potentiometer to the inputs of two comparators, one inverting input and the other non-inverting. I did the same with the motor's feedback potentiometer using the opposite inputs. The comparator outputs were fed to an h-bridge. I thought this would allow me to control the position of the motor without having to use a micro-controller. At worst I thought the motor would chatter as it kept trying to find the neutral point. What I got was more like Parkinsons disease because the motor would turn to the spot but shake continuously. I don't know if it's worth going any further. I would love to hear your explanation.
GREAT VIDEO THUMBS UP AND SUB. Just one not-to-important thing...COMPARATOR is pronounced: "COM-PAIR-ITTER"...where "ITTER" rhymes with 'HITTER' Sorry for the little nuisance.
An op amps can be used as a comparator but is not a comparator. An op amp has 2 comparators internaly built in so a comparator is much simpler than the op amps internal circuitry...
Did not get this. From what I was taught an OPAMP has a linear region. if you put a sine wave in over the linear region your get a sine wave out. A comparator runs high or low and will never be able to out put a sine wave only a square wave. I have been told never use an OPAMP as a comparator. I am confused.
What country are you in? I've never heard the pronunciation "compare-RAY-tuhr" before. You sound American but most Americans would use the pronunciation: ruclips.net/video/gpGg2R7artk/видео.html. Are you a British bristols watcher?
i love to see people taking time to explain the basics, thanks

I appreciate the refresher, it was clear, and easy to understand.

Thank you very much Sir for this detailed explanation... Appreciated.
Very nice and informativ introduction and explaination. Thanks.
great video,with a lot of useful informations ,thank you
Thank you very much for the refresher and the practical applications.
Nice illustration and clear explanation.
great video, sir you make understand so easy about comparator curcuit , thanks much.

I first learned the word in German then there are two versions on the web.

this is so easy to understand.. thank you for sharing.
THANK YOU VERY MUCH. VERY VERY USEFUL INFO.
So would one always need a sample and hold comparator to build a "true" ADC?
Don't know about "true ADC" but this is how many do work.

16:00 The low-pass filter (4.7K, 10uF) should yield an average of 2.5V at TP3, no (5V p2p, with 50% duty cycle, averaged out by the filter)?
Thank you.👍

Sorry for the little nuisance.
I know that. I first heard the term in German, not English. Thanks.
Compare-aetor?
Com-parator?

With no feedback it goes from all on or rail to rail. This mostly concerns op-amps design to be comparators.
Got it. Don't do feedback and the opamp works as a comparator. Cost effective? For a one off, maybe! Thx
Thanks a lot Sir
Very nice sir
great!!!!👍👍👍👍👍

What's the 4.7k resistor for?
The LM311 has an open collector output. The 4.7K resistor is a pull up resistor.
@@LewisLoflin Why doesn't the 560 ohm resistor serve that purpose?
@@km4hr The LM741 has a type of totem pole output while the LM311 has an open collector. Look at the schematics in the spec sheets.
do you have a book link to download
I didn't get this from a book I created it.
good video, but you drove me crazy calling a com-par-a-tpr acom-par-a-ra-tpr.
Wen ich das umsetze fallen alle vom zweig 😁

I picked my version up in Germany where I heard it the first time.
pronounced compare-a-tor NOT comp-a-rator
Thank so much 👍😊☺️🙂🤠🙏
