pygwb.coherence.calculate_coherence(psd_1, psd_2, csd)

Calculate a coherence spectrum given two power spectrograms and a cross-spectrogram.

Parameters:

• psd_1_spectrum (np.array) – PSD spectrum of first detector.

• psd_2_spectrum (np.array) – PSD spectrum of second detector.

• csd_spectrum (np.array) – Spectrum of the cross-spectral density of the two detectors.

Returns:

coherence: np.array
