timescales.sim.sim_lorentzian#
- timescales.sim.sim_lorentzian(freqs, knee_freq, exponent=2.0, offset=0.0, constant=0.0)[source]#
Simulate a Lorentzian with a timescale.
- Parameters:
- freqs1d array
Frequency definition.
- knee_freqfloat
Frequency corresponding to the desired timescale.
- exponentfloat, optional, deafult: 2.
Slope of the post-knee log-log spectra.
- offsetfloat, optional, default: 0.
Y-intercept.
- constantfloat, optional, default: 0.
Constant scaling factor that tapers high-frequency log-log power.
- Returns:
- powers1d array
Power spectral density.
