Appeal No. 2000-1887
Application No. 08/853,075
an error detector, responsive to the output signal and
configured and arranged to generate an error signal at least in
part as a function of the output signal and to provide the error
signal to the adaptive filter; and
a data processor, operatively coupled to the adaptive filter
and configured and arranged to
selectively modify the weighting coefficients in
response to the error signal,
selectively increase or decrease the number of
weighting coefficients used by the adaptive filter in
response to a characteristic of the weighting coefficients
used by the adaptive filter and no other weighting
coefficients, and
selectively allocate system resources for storing the
weighting coefficients.
The Examiner relies on the following references in rejecting
the claims:
Horna 4,377,793 Mar. 22, 1983
Sugiyama 5,517,435 May 14, 1996
Claims 1-29 stand rejected under 35 U.S.C. § 103(a) as being
unpatentable over Horna in view of Sugiyama.
Rather than reiterate the viewpoints of the Examiner and
Appellant regarding the above-noted rejection, we make reference
to the answer (Paper No. 14, mailed December 28, 1999) for the
Examiner’s reasoning, and to the appeal brief (Paper No. 12,
filed October 18, 1999) and the reply brief (Paper No. 15, filed
February 1, 2000) for Appellant’s arguments thereagainst.
