Hello everybody,
I am new on this website and I hoppe I choosed the right section.
If I am correct, the linewidth of a resonator 2Δf must be defined by the product of its damping rate γ and its resonance frequency f :
2Δf = 2.γ.f
In my case, I want to consider a strongly nonlinear oscillator, the frequency varies a lot with the oscillation amplitude. I already know that this nonlinearity will increase a lot the linewidth of the power spectra.
I wonder if such large the nonlinearity can also affect the linewidth of the oscillator when it is not excited (it becomes a resonator), and then be higher than 2.γ.f.
If you have seen this problem in any type of system I would be very happy :)
Thank you very much in advance !
