Good morning,
I'm trying to generate synthetic seismograms for an observed seismic event.
I did compare the amplitude in the time domain, and applied the FFT for both observed and synthetic waveforms.
although all the signals are beneath 0.3Hz, I'm asking about the tolerance range in the frequency domain.
How near the frequency ranges need to be in the FFT, to tell if my two signals are similar.
Thank you in advance
Thank you sir for your response, but in the FFT, should I compare the amplitudes or the range of frequency?
In the first , you have to just compare the amplitude spectra. However, some times working on complex waveform modelling is useful.
If you have enough time, please download Herrmann programme in seismology ,which is very helpful in waveform modelling.
