Im a physics undergrad from Spain and your youtube chanel is keeping me grounded to electronics through all of this abstract courses, thank you very much!

I love this as well as Aaron really goes heavy on the theory but also a bit on the history and other related tidbits to the circuit in focus

ha. "grounded"

Thanks again for the lecture. I forget a lot of this basics over the time.

your videos are greta! Keep 'em coming. By chance, just before your RC OTA video last week, I started working on a 4pole envelope follower for guitar based on this 4 pole RC with feedback topology, and it sounds pretty great. Nice to catch this video and validate my design after all

thank you for these lectures

Thank you Aaron, very interesting and looking forward to 4-pole OTA filters lecture. Can you also explain 2-pole OTA 12db filter while getting to the 4-pole? as many synths use them as well. Thanks

to make a long story short, a 2 pole has a lesser sharp cutoff and a 4 pole filter has a sharper cutoff. mutable-instruments.net/archive/documents/pole_mixing.pdf (page 3) mutable-instruments.net/archive/shruthi/build/4pm/

@@AnalogDude_ I was actually referring to designing the filter using OTA's, I'd rather listen to Aaron's lectures its way more interesting as his explanations are visual and easier to understand than any textbook.

@@peternotpeter i wanted to show you the difference between 2 and 4 pole, regardless of using an OTA or VCA chip.
