3. Consider the case where N
LBK
overlaps with N
3
(
N
3
≤
N
LBK
<
N
1
) and
N
LFWD
=
0
. In this case all
samples of N
3
are tagged as good and acquired. See for example Fig.
. The same happens in case
N
LBK
=
0
and
N
3
≤
N
LFWD
<
N
5
.
Note
: In this case there are two subsequent “GOOD” intervals.
