fooof.sim.transform.translate_spectrum¶
- fooof.sim.transform.translate_spectrum(power_spectrum, delta_offset)[source]¶
Translate a spectrum, changing the offset value.
- Parameters
- power_spectrum1d array
Power values of the spectrum.
- delta_offsetfloat
Amount to change the offset by, where:
positive values are an upwards translation
negative are are a downwards translation
- Returns
- translated_spectrum1d array
Translated power spectrum.
Examples
Translate a simulated spectrum, moving the offset up:
>>> from fooof.sim.gen import gen_power_spectrum >>> freqs, powers = gen_power_spectrum([1, 50], [1, 1], [10, 0.5, 1]) >>> translated_powers = translate_spectrum(powers, 0.5)
