传统双相激磁感应同步器数显表是直接通过测量感应信号中的相位信息来获取位移数据的,这会造成其抗干扰能力和其检测分辨率不能同时提高的问题。由此,介绍了应用差频解调技术,把原本为感应信号的相位信息转载到某一低频信号上,再把该低频信号作为被测信号来解决问题的原理,并提出了通过以数字与门和滤波器组成的电路模块来实现差频解调技术的具体方法。
The traditional two-phase induction sensor synchronizer digital display is to obtain the displacement data directly by measuring the phase information in the induced signal, which will cause its anti-interference ability and the detection resolution can not be raised at the same time. This paper introduces the application of the difference frequency demodulation technology, the original signal for the phase of the signal is reproduced to a low-frequency signal, and then the low-frequency signal as the measured signal to solve the problem principle, and proposed by the number and Gate and filter circuit module to achieve the specific method of the difference frequency demodulation technology.
