22 minutes and 36 seconds of exceptionally clear and concise circuit analysis- Something my Uni professor failed miserably to convey in over 2hrs- THANK YOU so much- You are officially a SUPER HERO
(late to the party I know) This is the most clear OP Amp tutorial to date, love the inclusion of the mathematical explanation almost everyone says "op-amp was used for math's" an None shows the actual math behind it. this is what an op-amp explanation should be 10/10 will watch many times and hope for more. :)
So, for me, this is a perfect video for this channel. The circuit theory is good, the maths is good, I like that. Don't want to make it like other channels. Thanks
I would think that a fairly simple filter output stage would go a long way to removing the harmonics from the "sine wave" to produce something very close to a true sine wave. Thoughts?
I really like enjoyed this. I'm not sure if I understood correctly but why are you getting distortion when the frequency decreases? As I understood it, you should get a constant gain under the frequency where it starts to act as a LPF? Instead the gain seems to increase to the point of distortion.
I truly appreciate your mathematical explanation at the end as an engineer because few vids actually go there with the calculus version if at all. I see why mathematically how the integration leads to what we see, BUT....not being an electrical eng (MS chem engr), ive basics of electronics. Though over time ive learned much into electronics self taught through vids and reading college books on the subject, i am curious: I see the integration at work, but no explanation on WHY this op amp layout integrates. Why does stage 2 give a varying output where first is digital (sq. wave)...I thought op amp out was either off or on, so how does 2nd out V vary w time as the out switches on and off?? Is the res-cap combo causing it to "see" varying V at this node of out2 as they drain/charge with time, through the 22k resistor at bottom left to ground...wouldnt this effect the V seen by op1 at its + input as well? Or, is there something going on with op2 thats causing its output actually to vary and my understanding of how they work as high (on) or low out only not correct?? I know im asking for overkill detailed breakdown, but I want to fully understand WHY this circuit does what it does for better usage in the future. Full understanding is a must with me...guess its the chem. engr. part of my brain that obsesses over this lol, but i cant help it. The not knowing keeps me up at night as my brain cant let it go... I understand you cant answer this in the comments without writing a short novel, so do you have any vids covering this aspect you could point me to? One last ?....an important electrolysis project ive built lacks one thing yet im incapable of building, a very specific power supply with specific out signal. Since this isnt high freq., can you suggest what could be capable of very high freq oscillation signal offset so it doesnt change polarity but pulses from 0V to several hundred V (or lower possibly) with adjustable freq control to some degree?? I need a high freq pulsing e-field between plate electrodes while keeping polarities of plates constant; this has postponed completion of this system for years as my understanding of electronics is vastly inadequate compared to the chemical and other understanding. Any advice would be very appreciated, thank you
Thank you so much . So that means you can make a pure sinewave inverter from a square wave inverter. But how do u really come to the resistor and capacitor calculator
Nice video thanks for sharing. What is the the range of the frequency, I need a variable frequency between 5 and 20 Hz sine wave, is that possible with this circuit.
when you change the resistance on the pot, it changes both the amplitude and frequency of the triangular and sine wave, how can we control each wave separately so its a more useful function generator. I would like some feed back on this point, thanks for the informative video, it helped a lot. please reply soon as possible. i based my design on thiis circuit.
Sir, could you please explain how you have applied the split power +/- 8 V to the circuit from the power supply? It would be helpful. Thanks for the video. It is quite educational.
13:00 - sorry, I can't get this math. logic here... I understand that V*t are adding on each t unit. So it comes V*t2... How does it comes divided /2 ? Sorry if I'm asking a silly question... 16:10 - and this "for an ideal op.amp" transformation explanation isn't clear... Ir = Vin / R is clear - Ohm's law. But why Ic is _minus_ C * dV0 / dt... can't understand it completely. It's a very informative video but I fear it's probably not so easy for high math. dummies like me :)
To first question, an integral is an area under the curve, and V*t is a linear function with a diagonal slope. That means when you're integrating that function you are calculating an area of a triangle with sides V*t and t which is 1/2*V*t*t, hence the half. I might be a tad late with my response, but I hope it helped anyway!
@@timecrystal5thapostleof125 yeah, I get it now, thanx! I don't remember if I've got it earlier )) I've ditched my DIY proto-synth yet... Beh gives us too much cheap synths 😅
On one hand I enjoy your tutorials. On the other hand, I come away not really understanding what you are trying to convey. Who is your target demographic? You seem to be reaching out to an undergraduate but upper level college division. It's definitely not targeted to the hobbyist. There would have been a time that I might have understood this. But now, decades away from my college years it's just not sinking in.
Thanks for your comment, you ask a good question as this channel is still finding its voice. On the one hand, a major theme is to understand circuits based on theory and practical demonstrations. On the other hand, I'm also a radio hobbyist and thus other videos simply examine radios and related electronics. I don't know that I'm targeting upper college division demographics per se, as opposed to people who are interested in the building blocks of electronic design and curious about different facets of electronics. Hobbyists and students alike are targets, as much as I think in those terms.
Radio Physics and Electronics I'm a hobbyist and I love your videos. Yes, it might get a bit complex sometimes, but having an insight on how the circuit works is crucial. If I do that, I find it easier to repair/design similar things.
I've never understood what the makers of this sort of videos think that the breadboard will convey. Only exception might be ben eater who does the breadboards so neatly that you can read them almost like schematics. Tom me at least the breadboard parts are totally useless. I do enjoy making one myself not watching other people. So, I'd wish people would just explain what the circuits do with the aid of the schematic diagram.
Thank you Consider becoming a Muslim if you're not :) When I see people who are helpful I remember the Prophet Muhammed peace be upon Him saying: "The best of people are those who are most beneficial to people."

Beautifully clear explanation of the integration function of op amp

Excellent video. The way you integrated the circuit with the math differentiates you from other channels 😉 Thanks.
Thank you!

Wow such a clear and fantastic video , now i can understand how circuit works 👍🏻👍🏻 thank u soo much

Good explanation of the square wave unit.

Nice video can u tell where to apply positive vcc and negative vcc or separate for every Op-Amp
From iraq thank you very much ❤❤❤❤
Very good👍👍👍👍 video thank you

will that circuit be ok to used as 1KHz sine to test audio amplifiers?
Enjoyed the tutorial Sir...please try to implement analog multiplier and divider using these opamp as log and antilog amps., if you get time

where are you getting all the resistors and capacitors values.we neesd the fomulas
Sir, could you please explain how you have applied the split power +/- 8 V to the circuit from the power supply? It would be helpful.
Thanks for the video. It is quite educational.
please what is the frequency range of this design
I want to know the components please
EXCELLENT PRESENTATION.DO HAVE A DEGREE IN ENGINEERING?
Thank you! My background is in applied physics.
Great!
Can I use any other op amps like LM741?
any.
Yes, other op amps should work.
please tell why square wave forms
All is good until i connect pin1 to pin6 then the waveform gets distorted and the triangle wave is nowhere to be seen
NIce !!!!
💯💯💯

It is challenging to be sure. Not necessarily out of reach, but it does require some extra work. Maybe Khan Academy will come in handy!
