ABSTRACT
We explore the chaotic behavior of a nonlinear electrical circuit
constructed with simple components such as diodes and linear
operational amplifiers. The circuit may be regarded as a nonlinear
analog computer that gives a nearly exact solution of a particular
chaotic model. Detailed comparisons between theoretical and
experimental bifurcation points and power spectra yield differences of
less than 1%.
