Spitz makes a better assumption for the signal
In real-world extraction of signal from data we are not given the
needed signal prediction-error filter (PEF). Claerbout has taken
the PEF of the signal, to be that of the data,
takes it to be
. Where noises are highly predictable in
time or space, Spitz gets significantly better results.
Theoretically, a reason is that the essential character of a PEF is
contained where it is small.
