The code simulates a nonlinear electronic circuit.
When a resistance is decreased the amplitude and hence the nonlinearity
effects increase.
The oscillations show a typical sequence of period
doublings and chaotic dynamics.
You can easily explore these for yourself with this code.
It displays phase-plane plots, return maps and bifurcation diagrams. It is both flexible and relatively easy to learn to use.
The simulation displays solutions to a third order nonlinear ODE.
Further details are described in an on-line information file.
A full write-up (i.e. Ch 10 of Korsch and H -J Jodl) is available
for loan in the teaching lab.
Note: Until a copy is placed on the NT Win95 fileserver ... a disk can be borrowed from Andy Alway in the teaching lab in order to load up the code on the PC you are using. You may also make your own copy of the disk for self-study.
