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.

1.基于非相关早减迟延时锁定环切载波跟踪环,得出了由一般形式的误差解表达式导出的码相载波相位跟踪误差曲。

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.

2.主区域都拥有可变DLL实现硬件间共享使用--如键盘数字转化器。
