page 733, “the equalization required varies from note to note.”
This necessarily means several key things:
(1) the equalization required varies from frequency to
frequency because inherently each note is a different
frequency;
(2) the frequency-bandwidth of the equalization required
varies from note to note because inherently the distance (in
hertz) between notes increases as one moves across the
musical scales.
Bartlett also teaches at figure 4 that there are significantly
different responses at different frequencies (notes). Thus,
equalization will require different gains at different
frequencies (notes) to compensate. As the Examiner pointed out,
Murayama teaches that a graphic equalizer is extensively used to
split the frequency spectrum into plural bands and to change the
gain in each band. Again, Appellant has not shown how the
Examiner erred in the rejection of claim 1.
Therefore, for the reasons above, we will sustain the
Examiner’s rejection under 35 U.S.C. § 103.
