Appeal No. 1998-0743
Application 08/214,169
In Engebretson, the sampling frequency data of a signal
is first decimated to reduce the amount of data supplied to
the processor, and after processing the signal, it is
interpolated to restore the frequency back to the original
value. Thus, Engebretson does not increase the sampling
frequency of a digital audio frequency electrical signal as
defined in cliam 7 but rather reduces the frequency and
subsequently restores it back to its original value.
Accordingly, even if there existed some suggestion or
motivation to combine the teachings of Lenhardt and
Engebretson, this prior art would not meet claim 7.
Whereas we will not sustain the rejections of any of the
independent claims over the prior art, we will not sustain the
rejections of the dependent claims.
REVERSED
