What is the natural frequency if steady state value is 0?

Hi all, How can I find the natural frequency of the signal attached? I thought to compute it from the equation wn=3/(ts*zeta), but MATLAB gives the settling time value NAN due to zero steady-state value. Thanks in advance.

The sketch doesn't tell many things. What else do you have about the signal and the system that generates it?

Hi Yunus,
As per my understanding, you are interested in knowing how to find the natural frequency of a signal. Whenever you're interested in frequency content of a signal, the Fast Fourier Transform is often an excellent tool to use. A Fast Fourier transform (FFT) is a highly optimized implementation of the Discrete Fourier transform (DFT), which convert discrete signals from the time domain to the frequency domain. FFT computations provide information about the frequency content, phase, and other properties of the signal.
To further explore about FFT refer to the below link
Hope it helps!!
