Summary#

Cheating to copy Scipy 1.2’s Welch method, to access the average attribute Note: Assumes fs is an integer in converting times to mask indices

Signature#

def scipy_12_welch(x, y = None, fs = 1.0, window = 'hann', nperseg = None, noverlap = None, nfft = None, detrend = 'constant', return_onesided = True, scaling = 'density', axis = -1, average = 'mean', mask = None, line_id_ver = 'old')
