1. Based on noncoherent DLL and arctan carrier PLL, the curves of tracking errors in general forms are given after a series of computing and simulation.
   基于非相关早减迟延时锁定环和反正切载波跟踪环,得出了由一般形式的误差解析表达式导出的码相和载波相位跟踪误差曲线。
2. There are variant DLLs for each of the main areas that may vary between pieces of hardware that share the same ASSP - such as the keyboard and digitiser.
   每个主区域都拥有可变DLL实现硬件间共享使用--如键盘和数字转化器。
