Once the bad samples associated with high-amplitude noise
are removed,
it is necessary to restore these samples, as well as the samples
that were not recorded.
The process used in this chapter is a modification of the
technique suggested by Claerbout 1995,
but it requires only a single filter to describe the signal,
as in the previous chapter.
In chapter ![[*]](http://sepwww.stanford.edu/latex2html/cross_ref_motif.gif)
, a method using filters that describe
both signal and noise will be used,
and the method of restoring missing data
that follows the approach in Claerbout 1995
will be used.
