Fibonacci All-Pass Filter Analog Computer

[@dariushsafari]

Very nice idea! Fibonacci numbers show up alternately across horizontal and vertical resistors. 21 Vy is across the the last R (Connected to Op Amp output) and Vo is actually 13+21=34 Vy.

Thanks for watching & for your detailed attention. You are right, the final line should state KVL as Vout = 13Vy + (13Vy/R + 8Vy/R)*R = 34 Vy 👍

Thank you for watching & for your insightful comments. Please note that the final line at the end of the video should state KVL as Vout = 13Vy + (13Vy/R + 8Vy/R)*R = 34 Vy , thank you 👍
