Logistic Maps and Analog Computing with Serge
video upload by La Synthèse Humaine
New Uses for Old Circuits Series
"New Uses for Old Circuits is a series looking at linear and nonlinear processes in the modular system.
In this video we look at the textbook example of a nonlinear and chaotic system - the logistic map. We explore how to use the Serge as an analog computer to take numbers and multiply, add, and subtract them, and further how to create a discrete feedback sequence from them.
Check out Greg Zifcak's website and his example of the Logistic Map: https://www.gzifcak.net/cefms/"
