摘要
移相是对输出波形相位的一种调整关系,其在通信、仪器仪表、甚至在导弹、雷达技术中广泛应用。同时两个同频率信号之间的移相,是电子行业继电保护领域中模拟、分析事故中的一个重要手段。本文从数学分析和EWB软件仿真两个方面入手,来讨论由RC组成的90o到-90o之间的移相电路。数学分析是从理论上讨论其实现的可能性,而软件仿真能够直观观察实验结果,利于提高结果的分析。
Phase shifter is a kind of relation adjustment of the output waveform phase, it is widely used in the communications, instrumentation, and even in the missile, radar technology. At the same time between two signals with same frequency shift, is an important means of accident simulation, analysis of relay protection in electronic industry. This article from two aspects of mathematical analysis and Simulation of EWB software, to discuss the phase shift circuit composed by RC from 900 to-900. Mathematical analysis is to discuss the possibility of its realization from the theory, and the simulation software can directly observe the result of the experiment, it help to increase the analysis results.
