徒弟:VCD与超级SVCD机的机心电路有哪些? 师傅:有些同行也把机心电路简称为伺服电路。机心电路通常用生产厂家的命名,目前最为流行的主要是:索尼、飞利浦机和三星机心电路,少数机器采用了三菱、东芝机心电路。徒弟:机心电路由哪几部分组成? 师傅:机心电路主要由机心控制电路、RF信号处理电路、数字信号处理(DSP)电路、伺服电路及驱动电路组成,如图23所示。表4列出了飞利浦CD6、CD7、CD7—2和索尼2549+2545四种机心电路主要集成电路及功能。机心电路发展方向是由模拟伺服电路发展到数字伺服电
Apprentice: VCD and Super SVCD machine movement circuit What? Master: Some colleagues also the movement circuit referred to as the servo circuit. Movement circuit is usually named after the manufacturer, the most popular at the moment are: Sony, Philips and Samsung movement circuit, a small number of machines using Mitsubishi, Toshiba movement circuit. Apprentice: What kind of mechanical circuit composed of several parts? Master: Movement circuit mainly by the movement control circuit, RF signal processing circuit, digital signal processing (DSP) circuit, servo circuit and drive circuit, as shown in Figure 23. Table 4 lists the four main ICs and functions of the Philips CD6, CD7, CD7-2 and Sony 2549 + 2545. Movement circuit development direction is from analog servo circuit to digital servo motor
