time and frequency measurement

Comparison between Analog and Digital Processing Method in Time and Frequency Measurement

模拟和数字处理方式在时频测控领域中的比对研究

It also introduces the development of time and frequency measurement and control techniques which are the most representative in the metrology area . It can reflect the relationship among instruments and the newest achievements of science and technology .

同时还就测试计量领域最有代表性的时频测控技术的发展、近年来在国际上的影响反映了仪器与测量技术与现代科学技术的最新成就之间的互为依存的关系。

It is an new approach of time interval and frequency measurement , which can be used to measurement short time interval by detecting the phase coincidence point between the signal and its transfer delay with related length .

这一理论利用信号的时&空关系通过对被测时间信号与其在长度空间上传输延迟的重合检测来测量短时间间隔，依此为基础可完成各种时间间隔与频率测量仪器。
