Spectral analysis

Identification of spectral properties in analog signals (e.g., the power spectrum).

welch_psd(signal[, n_segments, len_segment, ...])

Estimates power spectrum density (PSD) of a given neo.AnalogSignal using Welch's method.

welch_coherence(signal_i, signal_j[, ...])

Estimates coherence between a given pair of analog signals.

multitaper_psd(signal[, fs, nw, num_tapers, ...])

Estimates power spectrum density (PSD) of a given 'neo.AnalogSignal' using the Multitaper method.

multitaper_cross_spectrum(signals[, fs, nw, ...])

Estimates the cross spectrum of a given neo.AnalogSignal using the Multitaper method.

segmented_multitaper_cross_spectrum(signals)

Estimates the cross spectrum of a given neo.AnalogSignal using the Multitaper method on segments of the data.

multitaper_coherence(signal_i, signal_j[, ...])

Estimates the magnitude-squared coherence and phase-lag of two given neo.AnalogSignal using the Multitaper method.
