Experiments
1. Use RLC series resonance circuit to measure the inductance of a ferrite material at different currents;
2. Observe waveforms generated by a LC oscillator on an oscilloscope before and after RC phase-shifting;
3. Observe phase figure of the above two waveforms (i.e. Lissajous figure);
4. Observe periodic variations of the phase figure by adjusting the resistor of the RC phase shifter;
5. Record phase figures of bifurcations, intermittency chaos, triple times period, attractor, and double attractors;
6. Measure V-I characteristics of a nonlinear negative resistance device made of a LF353 dual op-amp;
7. Explain the cause of chaos generation using the dynamics equation of nonlinear circuit.
