The analog signal is compared with all the reference voltages at once by a string of high-speed comparators whose outputs are used to generate the binary output.
输入模拟信号立即与所有的参考电压通过一串高速比较器进行比较，高速比较器用于产生二进制输出。

Analysis result shows that the referencesignal can be highly precise and provide an adjustable performance if the given frequency of crystal is high enough.
The reference station needs to monitor and receive the high-accuracy navigation signal in the wide area DGPS, and to get more accuracy data of pseudo-range observation.
