APPARATUS AND METHOD OF DETECTING A TARGET PEAK VALUE AND A TARGET BOTTOM VALUE OF AN INPUT SIGNAL |
摘要 |
An apparatus of processing an input signal generated according to accessing of an optical storage medium is disclosed. The apparatus has a detecting circuit and a decision logic. The detecting circuit is coupled to the input signal for detecting a target peak value and a target bottom value of the input signal within a time period, wherein the time period is not less than a period of a reference signal generated according to accessing of the optical storage medium. The decision logic is coupled to the detecting circuit for determining a reference level according to the target peak value and the target bottom value.
