A digital data detection system, equipped with an interpolation apparatus, for generating decoded data by detecting information stored on a magnetic storage medium by interpolating sampled data using a phase difference signal and an interpolation coefficient is provided. The digital data detection system comprises a magnetic storage medium (10), an analog signal acquisition circuit (20), a pre-amplifier (30), an A/D converter (40), an interpolation circuit (410), an equalizer filter (420), a data decoder (430), and a phase error detector (450). The interpolation circuitry includes an accumulation block, a filter coefficient generation block, a HOLD signal generation block, and an interpolator. The interpolation circuitry (410) generates interpolated data using a phase error signal (PE) and an interpolation coefficient (W) provided from a MCU(Main Control Unit)(440). <IMAGE> |
