i purchased that course by the way!! lol im going to go invest in a wireless that gets power from ambient noise!
I don't know why I pay tuition fees when guys like you teach me more in ten minutes than I learn in a whole lecture. Thank you!
*Sits here frustrated studying for exams.
*Hears Pendulum - Slam
*Instantly becomes focused
Relatable
I came for the electronics, stayed for the Pendulum.
1.Very good explanation. 2. We can apply the knowledge as we want to. 3. In-depth and very clear explanation. Excellent.
Ya know, I'm a college physics student and i swear (not downing my professors they are great and I probably wouldn't have been able to pick up this stuff so well if it wasn't for them) that I have learned more from you than in my now 4th year of physics classes. You've helped with numerous of my "just for fun" projects. Thanks! And keep up the epic work.
Just wanted to say that your electronics videos are the most helpful I've seen anywhere! Thanks a lot for them, and please keep them coming!
On behalf of everyone who sees your videos, a big mega thanks to you, from all of us.
You put it all together for us, and make the impossible to learn, possible to learn.
If you had to learn this from some tenured professor in the fake education system we call universities, it would be impossible to learn anywhere near as much.
Your videos all have great production values, and you have an excellent voice on top of that.
Your videos inspire all of us to keep learning, and you make it easy.
I spent freaking two quarters to find out what the hell the different filters do and learned nothing form the class. but this video explained me what I need to know. Thank you so much Sir Afrotechmods. Keep up the good work!!!!
that was one of the most satisfying video tutorial ever....everything you said were on point and the use of practical approach instead of using equation stuffs just make this video so easy to understand. A big thanks and hug to you for creating such helpful video.
Wow! I ain't seen winamp since the 2000s and I ain't heard Pendulum in almost that long too. Kudos bro, kudos!
It's 2024 and this video is still the best one explaining the topic ! PLEASE restart posting videos, community needs such high quality material.
Man, your videos are QUALITY! Honestly, from all my experience from universities, books and other tutorials, your videos make the BEST intuitive sense. Excellent content, you can communicate the content in an EXCELLENT manner and very funny too! And most importantly, the mix of theory and practical stuff. Amazing channel, will await for more!!!
Yes surely good...
+1 for the Winamp
Very informative! I study electronics and I am finally beginning to understand this subject. And this video and explaination makes it way more clear to me.
Most practical & efficient presentation of the subject. Provides conceptual background to dive into more mathematical treatment.
BEST MOST SIMPLE "EXPLANATION" OF CROSSOVERS AND CROSSOVER "CAPACITORS" OUT THERE !
It is amazing that no one else can just explain this so simply ???
Most every question answered !
GOOD JOB !

OMG WINAMP! The memories...
+1 For Pendulum
Thank you. Thank you. Thank you. I was struggling with the damn thing for days! You've explained it so elegantly in such a short amount of time! Awesome!
Can you help me please i am playing 8ohm su woofer 400watts rms i want it to play 40hz down?IM CONFUSED what capcitor to use.
Daniella Henry
I'm not sure i understand what do you want to do, but i presume you want to filter out audio frequencies above 40Hz? I don't really work with audio but from what i understand you need to find out what the electrical parameters of the amplifier input are, as well as the signal source ones, and choose an appropriate resistor, so that your signal will transmit properly. When you know what resistor to put, choose a capacitor with c = 1 / (2*Pi*R*fc). My guess is that a 1k resistor might be enough. Then you'd need about a 4uF capacitor. Filtering is done on the pre-amp side i believe, not after. But like i've said...i'm no expert at this. For a professional solution you'd have to consult a professional.
I really appreciate your effort for making such useful videos.
Wow... another awesome tutorial... I've learned so much from watching these vids... It makes it so easy to understand the concept.
Thank you verymuch for this video! Explains everything in a clear, easy to understand way. THANK YOU!
Amazing video! you explain it so well and you even made this boring topic super interesting!
Thanks a million
That classic winamp ive been using for many many years and that put a smile on my face.
I'm doing these in Electronics at the moment. I already knew the basics, but thanks for the rest - keep the great videos up.
This was great, thank you. I used a RC filter to reduce noise on the 3.3v rail of my raspberry pi. It dropped the ripple from 25mv to less than 1mv.
BANGING explanation of RC low pass filters .......!!! Love it !!!
Excellent as always, and always so practical!
writing my dissertation at the minute thank you! great help and great channel
Best videos about on electronics on youtube
sir yr video on RC LOW PASS FILTERS TUTORIAL
An excellent video of the BEST quality that i have come across in my life. I can never forget this video because of its outstanding features like CRT viewing, hearing music variation at different frquencies, Practical demonstration of components and calculation, ideal graphs and Practical one, such a clear explanation of theory, what to say and what not to say. Very well made video.
thank u so MUCH

This is the explanation that I was looking for.. I wanted to filter out mobile incoming call frequency from my audio amplifier.. And this tutorial got me to it.
Insane explanation, best enough to clear out doubts
Super awesome video.. full of knowledge and way too different from bookish way of describing RC's. Thank you.
Really useful and the practical demonstrations were helpful, thanks.
Great as always! I've been waiting for you to make a filter video. Thanks!
You got my thumbs up for putting Pendulum music!
Really helped me understand, I'm with seth, I've been at Access to Music college for 3 years and i've learned more in this video then i have in all 3 years at college :L Really good, thanks alot man :)
Your videos are the best! Thank you
Helpful, instructive video, thanks for making!
Wow, I just say wow when I've leanred something new even years are gradualting engineering.
Brilliant tutorial. Every other one I've seen or read just uses random resistor values. Your's is the only one that states WHY you're using those values. Sub'd
wasn't expecting pendulum when doing my circuits hw! haha thanks brother
Good vids, keep it coming. I learn a lot from your vids.
aaaahh, takes me back to highschool... Thanks for these vids man!!
This is amazingly explained! I have to write a paper about an experiment about high pass and low pass filters that I was supposed to do at university but this whole situation has put that on the hold but not the paper I have to write ahaha thankfully there's resources such as this where I can actually see what I would be doing! Thanks!!
Hey buddy...do you maybe have that paper written and would you be willing to share it, as i have to do the same thing too hahaha
@@aljazmarolt This was a long time ago but I'll look over my stuff and see if I find something ;)
@@aljazmarolt I can't seem to find anything :/ And if I did it would probably be written in portuguese (my mother language). I do have some python code using high and low pass filters for optics applications though
You deserve a medal
What I used for a treble roll off filter was a 0.01 mfd capacitor in series with a 500,000 ohm potentiometer across the transformer out of the headphone jack of my hp XP windows desk bound computer. I got the parts from an industrial electronics store bin.
I used that as an auxiliary control. That fed an amplifier, which fed a parametric equalizer. It was just a whole lot easier to take my hand and turn the highs up or down, rather than fiddle around and go into the computers dedicated audio equalizer, which was optimally set.
It works great. When the highs go down, the bass goes up a little. I'm mainly concerned about speech intelligibility in movies that I watch.
I mounted the little RC circuit in a small plastic box. I like it because IT'S HANDS ON! I don't have to go through the keyboard commands.
The fact you played pendulum is an insta-thumbs up
Excellent tutorial, keep up the good work.
Best. Anonymous. Video. Ever! You guys really do help the world
Your vids are awesome!
Keep it up.
afro tech mods sharing quality music, Im gonna add it to my playlist
very nice example of low n high pass filter.. with a win amp :)
Best example song for sure i love Pendulum
BEST... TUTORIAL... EVER. And great song choice!
Great video, I was not able to understand this whole topic, but after watching your video. :D
Thumbs up because of 6:19 and because this is actually a good explaination
Thanks
Hi, I made a subwoofer and I turn it right up because I think people like it, but it rattles the rusty doors off my '87 Buick, any suggestions?
Chuck Norris Dynamat that rust bucket
Is that anything like Dynamite?
Has onyone actually noticed it's basicaly a response to one older comment?
very good tutorial, i learned so much
Great tutorial 👌
Thank you, your videos are very helpful.
this video deserves double like
Thanks for your videos where people founds many useful informations :)
Nice. I had both an original and an unorignal power supply (9V output) for a guitar pedal (distortion pedal), but the unoriginal power supply made this guitar pedal generate a high pitch noise which wasn't there with the original power supply. For fun I used a 120 ohm resistor with a 10 uf capacitor and then connected the pedal to the filtered 9V - lo and behold - all the high frequency noise vanished.
I'm still sticking to the original power supply, but this sure was an interesting experiment 😃
BEST TUTORIAL EVA!
Maximum points for using classic winamp. :D
Thanks for the videos Afro, you rock.
This was so helpful. Thank you
thanks, your videos are really helpful.
i learned more from this mans vids than i ever have in electronic classes.
Awesome video sir
simple and straight to the point. thanks
Awesome Video!
I LOLed at the soft low pass and high pass xD
Thank you so much!!! Explained beautifully
Brilliant vid. Cracked up at 6.23
Very clear. Thank you. On to high pass and LC.
AAAAHHHH PENDULUM!! rock it, afro
Thanks for saving my life from high frequencies!!!!! Great vid

“Winamp winamp winamppppp
It really whips the lamas ass”
Underrated comment!
Simply amazing.
0:25 damn that is some 2010 shit going on right there 😄
These videos are perfect, btw. I took classes in electronics and have let the majority of it wither away in my brain. Thanks
very nice.. very useful video
Great video!
Great video. Nicly explained...
Thank you.
Great clip, thanks.
one question , according to your experience, how do you usually decide the cut off frequency to a equipment ?
I am using PLC at the moment, I am recommended to use RC filter to deal with noise problems to the input of the PLC,but I have no clue how to decide cut off frequency
