equalizer (B103) shown in figure 3. See Specification, page 11,
lines 24-25, and page 36, lines 19-24.
The adaptive equalizer (B103) comprises an FIR filter (C100)
having a plurality of filter coefficients (C116). See figures
8B, 8C, and specification, page 35, lines 19-21, page 37, line 2.
The adaptive equalizer (B103) is further responsive to an error
value, ek, (C112) computed as a function of the output (Yk +t)
(B102) of the FIR filter (C100) and an estimated ideal value (~Yk
+t). See figures 8B, 8C specification, page 36, lines 4-10.
Additionally, the adaptive equalizer (C100) comprises an
interpolation circuit (C106), responsive to the interpolated
sample values (Yk +t) (B102) for generating the error value, ek,
(C112) synchronous with the discrete time sample values (Xk)
(25). See figures 8B, 8C, and specification, page 36, lines
10-18.
The only independent claims 1 and 17 present in the
application are reproduced as follows:
1. A sampled amplitude read channel for reading digital data
from a sequence of discrete time sample values generated by
sampling an analog read signal from a read head positioned over a
magnetic medium, comprising:
(a) a sampling device for sampling the analog read signal
to generate the discrete time sample values;
