Appeal No. 1999-2688
Application No. 08/751,057
Even so, each of the instant claims requires that the
respective frequency be "stored" under each address of the
data memory and the examiner has not convincingly pointed to
any suggestion, within Gray, for storing any "frequency" of
IQ values. While we agree with the examiner that the look-up
tables (LUT) of Gray are memories, it does not appear from
Gray’s disclosure that a "frequency" is stored in the LUT.
Rather, the LUT converts complex data to 8 bit phase and
magnitude data. The output of the LUTs, in Gray, can be made
proportional to phase or frequency [column 6, lines 49-50],
but while the LUT outputs may represent frequency values,
there is no indication that Gray stores these frequency
values, as does the instant claimed invention, and the
examiner has pointed to nothing that would have suggested that
it would have been obvious to do so.
