The hardware electronic circuit of the Duffing oscillator has been designed using Op-Amp IC
LF356, 4-bit analogue multiplier AD633JN, carbon resistors and ceramic capacitors. The
circuit runs on a 20V function generator which is capable of producing noise too.
Here's a list of interesting problems I've worked on:
- Observed the output signal at F=159Hz and varied amplitude of function generator.
- The introduction of noise in the system.
- Establishment of coherence resonance up to a certain noise level.
