Extracting the sine from the square wave is something I’ve had to do at work. I’m an embedded software engineer and for a controller I had to write we were measuring what was essentially a square wave and we needed to feed as a sine wave into our controller, so we using a FIR filter to brick wall chop off the harmonics of the square waves fundamental. We knew the expected fundamental frequency, so we could tune the filter to cut off just how we wanted.
Your content scratches a special itch in my brain. As an electrical engineering major in college who plays music and knows some theory, your content basically feels tailor made for me. God I'd love to grab a beer with you
Human perception is surprisingly precise. I don't have a citation but there are countless books on graphic design and data visualization that teach about how accurate we are at determining if lines are parallel. It's a big factor in UI design as well, really powerful user interfaces make use of the parts of out visual perception which work the best. Another one is our ability to tell if two parallel lines are coincident, which you use every time you read the speedometer in your car, or the fill level on a measuring cup, or in this case when you want to make sure what you're seeing is a smooth wave without any lumps.
Which makes me wonder how accurate it would be if you would somehow automate these adjustments and take measurements on a fine scale and take the optimal amplitudes that way. Although I can imagine the other factors adding error might be more significant than the errors introduced by eyeballing it.
@@B0K1T0probably eminently automatable with HPIB instruments tbh, on both the signal measurement and generation side! Could log many dozens or hundreds of samples for each waveform and setting as well.
This is amazing content. Love how you tie together many topics in a satisfying way. I could listen to you for hours, you have an amazing voice. Keep up the good work, you deserve way more.
Genuinely baffling how small your audience is considering the quality of your content. You deserve way more, hopefully you'll get it, keep up the good work :)
Everyone else is saying the same thing, but this channel is so good. You describe things so well that people who don't know about it can understand, while also leaving enough detail in that people who do know more can gain more from the video, and that is an incredible talent.
You are such a gem! I love your content, how you manage to tie together seemingly unconnected fields of maths/physics/engineering. And on the way made me laugh out loud several times in this video! Please keep up the great work and consider setting a patreon for your channel, I would love to support your work.
I don't know if I missed something but you should've been able to run the low pass resonance filter on the sin wave too, instead of needing the triangle wave... Regardless, great video
Thank you for what you do! Really interesting and great how you thought of how to do something strange that you were curious about, tried a few things, problem solved and then solved the problem. And even being able to share this with us in a coherent and fun-to-watch video. As some have also commented, This has been my new favourite channel on TH-cam recently. Please keep exploring the wondering world we're in with maths and physics!!
Man i am so glad I found this channel. I do data analysis, and this bings a fun perspective to my work and studies. I actually started a "popcorn-project" in the same vain as your video a couple of months ago, which i fnid very fun. This video sure is giving matt parker a run for his money. Good job man!
I really like the production of this video! Very nice visuals. I just noticed the de-essing work you did actually made some words unintelligible. Not a huge issue, but one I thought you'd want pointed out for the future. Love the content, keep it up!
this is really cool and i followed along with my microbrute lol, i do wish you showed exactly where you were turning the knobs to though. it's actually kinda neat to get a really simple sine wave out of this usually very crunchy and complex synth
I just realized that this channel is like really new, and it's fucking awesome!! Keep up the good work!! (and may the mighty gods of the algorithm favor you)
Hey man, I just found your channel and have watched a couple videos and am absolutely in love! I love what you do and how varied it is. Also, on a side note, what is the song you use at the end of your videos?
Hey! You should try this again but generating from a DAW like Ableton. The built-in EQ-8 has decent HPF capabilities, but Fabfilter Pro-Q would knock it out of the park. Total overkill but it’d be fun.
You can get a higher shelf/less inclusive filter on a software synth, at least I know on phaseplant there is a specific function on the filter effect on it. Good luck on your sine adventures
Brilliant idea: performing the whole experiment using a plug-in should generate much more repeatable and accurate results! (Probably best to do this with a pretty simple naïve synth though, without complex virtual analogue circuit modelling.)
Awesome vid as always... 👍👍 say... can we relate / combine this theory with the financial market? I mean... market chart looked just like this.. moving sideway or up n down😁
Fourier transforms and Fourier series are so universally useful that I feel like I should explain it in almost every video, and this explanation was lightning fast, so I'll definitely cover it again!
The Biblical accuracy of pi might be closer than you think: we assume of course that they'd work to 21st century standards and measure the circumference and diameter from the same points, but perhaps that assumption isn't entirely safe. Later the Sea is described as "like a lily blossom", and checking images we can see lily blossoms are splayed. So if the top of the Sea splays out then it could well have a body circumference of 30 cubits and an outer diameter measured at the rim of more than 9.55.
Hmm…. Would it be plausible to say the synthesizer you own possibly was not made correctly? This could turn out to be a new method for ‘tuning’ future synthesizers

yep, FIR filters are wonderful. I used to use reaFIR to reject hypersonic frequencies in my music before converting to MP3.
@@ampersand64 to shrink the file size?
@@realityChemist prevent aliasing. Maybe I'm dumb and regular mp3 encoding already does this.
I did it a while ago, when I knew less about production.
I like your funny words magic man
If you already knew the fundamental frequency isn't the sine wave already known?

Honestly quite impressive that you were so close with the eyeballing on the oscilloscope

This is an amazing physics solution. After all, know that pi=3.
this is by far one of my favorite channels on this website. keep making the awesome content!
I came away from this finally knowing why square waves are made up of only odd harmonics! Great video!
Brilliant! Thanks for making this. I need these videos in my life 🎉
great channel mixes every thing i love : math music animation.
I don't know if I missed something but you should've been able to run the low pass resonance filter on the sin wave too, instead of needing the triangle wave... Regardless, great video
That model of synthesizer doesn't have a Sine oscillator
Man, I've always known this stuff and the maths behind sound but I've never quite thought of how I could reverse it to calculate PI. Great work!
Makes my day better after a class test
Lifelong music producer. Understand exactly 0 of this.
A+ 👏👏👏
You could use better filter with steeper cutoff, but I really appreciate your solution 👍
This channel is popping off hard.
I really love how, in single video, you can interest me with topics, that I'm totally terrible with; trigonometry, music and electronics :) thx
4/5ths of my youtube time is spent o. Either synths or maths. This hit my niche just right. HAPPY PI DAY
this channel is a great concept

The synthesizer did a better job than the Bible
I am gonna take that quote
And I will use it

Your style and music choice are top notch. Love the content! :3
The SUB oscillator should be sine wave on the Microbrute. On the Minibrute, you have a choice switch that can be changed between sine or square.
Your videos are so calming and therapeutic
Its OK, you just found Engineer's Pi

Matt Parker: First time?
I love your content so much! I love your voice, how you speak and the drawings are so good too.
Love what your doing man :)
Hey man, I just found your channel and have watched a couple videos and am absolutely in love! I love what you do and how varied it is. Also, on a side note, what is the song you use at the end of your videos?
I'd also like to know
Great video. I played it really loud with the windows down so the birds could hear it.
Hey! You should try this again but generating from a DAW like Ableton. The built-in EQ-8 has decent HPF capabilities, but Fabfilter Pro-Q would knock it out of the park. Total overkill but it’d be fun.
You're a mad genius. Love this channel
As soon as i saw the waveform i knew you were gonna talk about harmonics lmao nice video
Oh great, physics and synth content? Looks like that even after the first glance, it checks all the boxes ;)
Pi day woooo, love your vids btw :)
I dont know why but I find him just so cute explaining me physics
The sparrows at my balcony approve.
GOD HAS SPOKEN ONCE AGAIN, and now imma eat and listen
I don't think that anyone noticed, but I love the attention to detail in this video. It is also exactly 2*pi minutes long :D
Well, not *exactly*...
10 seconds off mate
finding this channel feels like when I found real engeneering

Classic Low Pass VCF Nice analog synth you got there
birb with pie is wholesome
I’m a filmmaker and I think the audio editing process is fascinating so it’s neat to hear and see the math of how audio works
Awesome vid as always... 👍👍
say... can we relate / combine this theory with the financial market?
I mean... market chart looked just like this.. moving sideway or up n down😁
"one of the worst ways of measuring pi" I'm dying xD
cool video ! 👍
Happy pie day !
I LOVE THIS CHANNEL
New video Yayyyyy:)))🌹🌹🌹
Thanks for the video! Very enjoyable 😁
happy pi day you funky nerd bird❤
Great content
These BIRDS ARE SO EPICX
this makes me want to play with my grandmother moog and play with the classic ladder vcf lmao
You got it close enough for engineering 😂
Can you please do a whole series on this 🙏
what kind of succulents you got running with your synth setup?
Thanks! Now I understand the sine func*Hn
Nice video, could you make a video that explains Fourier transformation in more details for a bird? 🐦 Really appreciate it!
Fourier transforms and Fourier series are so universally useful that I feel like I should explain it in almost every video, and this explanation was lightning fast, so I'll definitely cover it again!

I can’t believe this man’s really animated traditional grip on a bird 5:42

I’ll take your word for it lol
AKA db -12 db-24 stuff for the vcf
truly a birbin moment
birbin frr
no cap frfr
cool video but it went over my head compared to your other stuff - time for a rewatch !
birbs are HEKIN COOOOOOOO
I'm absolutely love u, mate
All these calculations to find out what engineers knew all along, pi = 3
I want the song towards the end
Did you compose your ending song? I really love it.
Yep!
@@physicsforthebirds if you ever write a full version, I'd buy it in a heartbeat 💓
Now we know what pi sounds like
synthesis nice 😎
Omg this is crazy cool
I HEKIN LOVE BIRBS WHO DO PHYSICS
2Pi shows up more often than 1Pi... Why is it Pi and 2Pi and not Tau and Tau/2?
I LOBE YOUR CONTENT
omg whats the credits song

I have seen so many among us memes that it took me 5 seconds to realise its a bird on the thumbnail
What oscilloscope do you have?
