Signal processing apparatus, signal processing method and storage system

摘要

A signal processing apparatus has a plurality of baseline wander correcting units, provided in a processing path in which a predetermined processing is performed on an input signal. Baseline wander of the signal is corrected sequentially by each of the plurality of baseline wander correcting units. At least a baseline wander correcting unit placed in the initial stage may correct baseline wander by a feedback control. The baseline wander correcting units correct the baseline wanders, respectively, so that the wander of baseline can be efficiently corrected.
