A further teaching that coefficients in memory 13 are
from previous data patterns is to be found at column 5, lines
41-65. There, Kim discloses that coefficients stored at 13b-
13n are derived by utilizing the coefficient from initial
coefficient location 13a “… as an initial filtering value when
a certain channel is firstly selected and then obtains a
filtering coefficient converging on the corresponding channel
according to the inputted coefficient.” (emphasis added).
Accordingly, with respect to claim 1, Kim Figure 6
teaches a control means 8, 9, 9a and 11 for controlling
filtering properties of first filter means 4 and second filter
means 6, wherein the control means 8, 9, 9a and 11 controls
filtering properties of the first filter means 4 based on
previous data patterns in the input signal received by the
first filter means (the input signal underlined, above). With
respect to claim 11, Kim Figure 6 teaches selection logic unit
8, 9, 9a and 11 connected to first finite impulse response
filter unit 4 and second finite impulse response filter unit
6, wherein the selection logic unit controls the first finite
impulse response
filter unit 4 and the second finite impulse response filter 6
