Asymmetry compensator for partial response maximum likelihood (PRML) decoder |
摘要 |
An asymmetry compensator for a partial response maximum likelihood (PRML) decoder, which is utilized to remove and eliminate the asymmetric component of the regenerating signal read from the optical recording medium, thereby effectively solving the problem of the asymmetry of the optical disk regenerating signal. The compensator includes an offset controller and a gain controller. The offset controller determines the central level of the regenerating signal thus to adjust the offset of the regenerating signal while the gain controller is arranged to adjust the gain of the regenerating signal.
