摘要
提供使用一个中央控制器控制双高频调谐器数字电视机的设计方案．它采用新型ＰＬＬ内藏式电子调谐器作高频调谐，以通用芯片８０３１代替专用芯片ＣＣＵ来设计硬件控制系统．着重阐述中央控制单元及控制电路和电子调谐器．
A desing of controlling digital color TV with double high-frequency tuners by a central control unit is presented.A new PLL internal-hidden electronics tuner is selected to serve as high-frenquency tuning.The hardware of control system is set uq by general chip 8031 instead of specific chip CCU.The central control unit and the electrinics tuner are given emphasis in this paper.
