POLARIZATION DIVERSITY FOR OPTICAL FIBER APPLICATIONS

摘要

An apparatus including sensors that aid in the location of a stylus within thegroove of a rotating record. The location of the stylus corresponds to aportion of an audio waveform present at a unique location within the groove.Using the correspondence between the location of the stylus and the portion ofthe audio waveform, an external digital source may be synchronized with ananalog waveform. A high speed digital data path connects a control unitincluding a turntable platter to signal processing unit. Software in thesignal processing unit synchronizes the analog waveform and digital signalsfrom the external digital source.
