资料介绍

介绍一种用数字集成电路实现的伪速率调制器及其应用.该调制器用一片FPGA实现3个通道的伪速率调制器.有别于用软件或模拟电路实现的方法,该调制器用数字电路实现,其中一阶环节通过移位算法实现指数运算,简单灵活,既克服了模拟电路和软件实现的缺点,又具有模拟电路实时性高、精度高以及软件实现方式方便灵活的特点,适用于整星信息一体化和综合电子技术的卫星控制系统体系结构.

One kind of pseudo-rate modulator designed with digital integrated FPGA and its application are introduced. Only one integrated digital chip is needed to integrate three-channel modulator. This modulator is designed with digital circuit, and is different from that designed with analog circuits or soft- ware. The exponent operation of the one-order feedback logic is substituted by digital shift. It has the same characteristics of high real time, high precision compared with that implemented by analog circuits, and has the same characteristics of convenience and flexibility compared with that implemented by soft- ware. This modulator can overcome the shortcoming of that implemented by analog circuits or software. It is applicable to the satellite control system...
