光盘驱动器的信号处理装置及方法
摘要：
本发明提供一种信号处理装置，该信号处理装置包含取样/保持单元以保持复数个模拟光感测信号。信号保持控制单元产生控制信号至控制取样/保持单元以保持模拟光感测信号。模拟调整模块调整被取样的模拟光感测信号的偏移程度。一多工器选择性地耦接其一输入端至该多工器的输出端以输出调整后的模拟光感测信号。一模拟/数字转换器转换调整后的模拟光感测信号为数字光感测信号。
摘要（英）：

The present invention provides a signal processing device which comprises a sampling/maintaining unit in order to maintain plural analog optical sensing signals. The signal maintaining control unit generates the control signal to the control sampling/maintaining unit to maintain the optical sensing signal. An analog adjusting module adjusts the sampled analog optical sensing signal. A multiplexerselectively couples one input end to the output end of the multiplexer to output the adjusted analog optical sensing signal. An analog/digital converter converts the adjusted analog optical sensing signal to the digital optical sensing signal.
