频率计

A lot of excellent circuits can be quickly and easily designed by using of Multisim2001. This thesis designed digital answer bell, digital frequency meter, up-down-counter, adder- subtracter .

本文利用Multisim2001在数字电路方面的仿真能力，设计出了数字式抢答器、数字频率计、正序倒序计数器、个位数的加法减法器。

This subject has mainlyexplained that chooses integrated circuit as the key device, hasdesigned a simple and easy digital cymometer, regard trigger andcounter as core , input , separate by signal frank , touch off ,count circuit , data processing , data reveal module of functionmake up.

本课题主要选择以集成芯片作为核心器件，设计了一个简易数字频率计，以触发器和计数器为核心，由信号输入、隔直，触发、计数、数据处理和数据显示等功能模块组成。

The accuracy of receiver clock parameter got from point positioning is not high enough to be introduced into the double difference equation. In order to get the accurate receiver clock error, high quality cymometer will be needed, while this is not applicable for the real work.

由于用伪距求得的接收机钟差不能满足精度要求，要想精确求得接收机钟差，需要高精度的频率计，这在实际应用中难以做到，而求解参考卫星站间单差模糊度的方法则是可行的。
