BUI (δ-δ)

When the Tail Fit separation method is selected (see Separation Method), the BUI (δ-δ), Bounded Uncorrelated Interference Delta-Delta, measurement shows how much of the deterministic interference (DI) is uncorrelated to the data pattern.

When the Spectral separation method is selected, all DI that is uncorrelated to the data pattern is reported as periodic interference (PI).
