pygwb.util.calc_bias
- pygwb.util.calc_bias(segmentDuration, deltaF, deltaT, N_avg_segs=2, window_fftgram_dict={'window_fftgram': 'hann'}, overlap_factor=0.5)[source]
Calculate the bias factor introduced by Welch averaging.
- Parameters:
segmentDuration (
float) – Duration in seconds of Welch-averaged segment.deltaF (
float) – Frequency resolution (in Hz) of Welch-averaged segment.deltaT (
float) – Time sampling of Welch-averaged segment (in seconds).N_avg_segs (
int, optional) – Number of segments over which the average is performed.window_fftgram_dict (
dictionary, optional) – Dictionary with window characteristics. Default iswindow_fftgram_dict={"window_fftgram": "hann"}.overlap_factor (
float, optional) – Defines the overlap between consecutive data chunks used in the calculation. Default is 0.5.
- Returns:
- bias:
float The bias factor.
- bias:
