Presentation Transcript

  1. Square Pulse Analysis of Nonlinear Resonance A. Keller and S. Bhattacharya

  2. Goals Testing square wave pulse method Understanding the origin of the non-linearity in the RLC circuit Studying the effects of multiple non-linear RLC circuits in a ring lattice.

  3. Method “Excitation” Circuit adjusts to find new equilibrium Similar to a spring with a magnet. Voltage time

  4. Linear Harmonic Oscillator

  5. Varactor diode RLC

  6. Linking Inductor Node Ryan Stearrett and L Q English, Experimental generation of intrinsic localized modes in a discrete electrical transmission line, J. Phys. D: Appl. Phys. 40 (2007) 5394–5398

  7. Conclusions • Square wave method is an effective method for determining resonance of a circuit • Varactor diodes introduce non-linearity in resonant circuits. • Multiple non-linear resonant circuits create an anharmonic response dependent upon voltage (~3volts).
