HD DVD wobble detection circuit |
摘要 |
A circuit including a wobble signal phase imperfection detector configured to detect and correct a phase transition imperfection in a first scaled wobble signal sample. The wobble signal phase imperfection detector includes an integrator configured to integrate the first scaled wobble signal sample over substantially a half-period portion of the wobble clock signal, and a selector configured to select as an output either i) the first scaled wobble signal sample integrated over substantially one period of the wobble clock signal or ii) the first scaled wobble signal sample integrated over substantially the half-period portion of the wobble clock signal, wherein selection of the first scaled wobble signal sample integrated over substantially one period of the wobble clock signal indicates that the phase transition imperfection does not exist with the first scaled wobble signal sample.
