Windows semaphores are counting semaphores , which can be used to control access to a pool of resources Windows信号量是计数信号量,可用于控制对资源池的访问。
Thus the principle to deal with the four basic waveforms is put forward and a new phase - demodulation circuit is designed . experiments for the two circuits on same gyros are made and they indicate clearly that the mdrlg ' s null - shift problem consists in the faultiness of the old phase - demodulation circuit 在此基础上,提出了处理计数信号过锁区波形的基本原则,进而设计了新的鉴相电路,并在同一陀螺上对两鉴相电路进行了对比实验。
Firstly , computer model of mdrlg is set up for simulation purpose . by simulation about the two output signals of mdrlg , four basic waveforms between the two signals in lock - in area are found out and the fact is discovered that the old phase - demodulation circuit introduces errors when it is used for demodulating two of the four basic waveforms 本文首先建立了机抖陀螺的计算机仿真模型,利用该模型对陀螺两路计数信号及原有鉴相电路进行了仿真,发现两路计数信号过锁区时存在四种基本波形,且原有鉴相电路对其中两种波形产生鉴相误差。
