Chua's circuit
Leon Chua's circuit uses an operational amplifier to simulate a negative resistor
(in a small range). This is the nonlinear element necessary for chaos.
The SMU Physics version was designed and constructed by Ken Ueda as part of our
Undergraduate Research.
It includes a speaker to hear the period doubling, chaos (noise), and period 3.
