发明名称 SIGNAL PROCESSING DEVICE AND SIGNAL PROCESSING METHOD
摘要 <p>The present invention is directed to a signal processing apparatus adapted for correcting non-linear distortion of a reproduction signal, which comprises a secondary adaptive equalizing filter (16) connected in parallel with a primary adaptive equalizing filter (15) in order to correct non-linear distortion that an analog equalized signal x0(k) has. Filter outputs of the primary adaptive equalizing filter (15) and the secondary adaptive equalizing filter (16) are added at an adder (17). The added output thus obtained is delivered to a phase interpolation filter (18) as an equalized output y(k). The phase interpolation filter (18) performs interpolation of phase on the basis of a filter output of the primary adaptive equalizing filter (15) and a filter output of the secondary adaptive equalizing filter (16). A filter output of the phase interpolation filter (18) is delivered to an ITR-PLL circuit (19). &lt;IMAGE&gt;</p>
