Application No. 08/132,969
description in the specification. In response, Appellant
(Brief, pages 7-9) refers to the description at lines 1-11 of
page 10 of the specification which describes the establishment
of the output voltages of the D/A converters 4 and 5 between
maximum and minimum values of the voltage sources in
accordance with the digital input signals D and D . In4 5
Appellant’s view, the separate nature of the digital inputs to
the D/A converters 4 and 5, along with the ability to
establish a range anywhere between maximum and minimum values
of the voltage sources, supports the independence of the
various digital inputs to the three claimed D/A converters.
Upon careful review of the claim language in question in
light of Appellant’s disclosure, we are in agreement with the
Examiner’s position as stated in the Answer. In our view, no
support on the record exists for Appellant’s conclusion that
separate digital inputs to the D/A converters 4 and 5 would
necessarily imply the independent nature of those inputs. In
addition, the range setting ability of such digital inputs
supports no conclusion of independence as well. We note that
the Examiner, in further support of his position, refers to
the equation at page 5 of the specification, also reproduced
