专利汇可以提供Clock reproducing circuit of disk player专利检索,专利查询,专利分析的服务。并且PURPOSE:To simplify the constitution of a clock reproducing circuit by using a pulse generating part containing a master clock pulse generating part and a dividing counter to produce a bit clock pulse which is needed for demodulation of a read reproduction signal sent from a rotary disk to which digital signals are recorded. CONSTITUTION:The output terminal of an edge detecting part 4 is connected to the load terminal L of a dividing counter 10 consisting of M-bit counter (M: positive integer such as 4, etc.) for an 1/2M dividing action (1/16 division, etc.). At the same time, the output terminal of a master clock pulse generating part 13 is connected to a clock terminal CL of the counter 10. An output terminal 14 is led out of the output terminal of an inverter 12. The read output fed from a revolving digital audio disk is obtained from an information reading means 1. This read output is amplified up to a prescribed level by an amplifier 2 and sup- plied to a waveform shaping part 3. Then a read reproduction signal S is obtained at the output terminal of the part 3.,下面是Clock reproducing circuit of disk player专利的具体信息内容。
