decorrelation_ratio#

caput.util.pfb.PFB.decorrelation_ratio(delay: numpy.typing.ArrayLike) numpy.ndarray[numpy.float64][source]#

Calculate the decorrelation caused by a relative delay between two timestreams.

This is caused by the fact that the PFB is generated from a finite time window of data.

Parameters:
delayarray_like

The relative delay between the correlated streams in units of samples (not required to be an integer).

Returns:
rationdarray

The decorrelation ratio.
