The experiments also show that the new circuit can deal with the four basic waveforms rightly and has the advantage of high resolution , high capability of rejecting noise , simplicity , and so on 实验表明:新鉴相电路能正确处理四种基本波形,且具有分辨率高、噪声抑制能力强、电路简单等优点。
The method to get the parameters for each basic waveform was given by choosing the sine window function waveform as the basic waveform , and based on the srs time - history synthesis principle 依据冲击响应谱时域合成的一般原则,选择合成小波中的正弦窗波作为基本波形,给出了确定各基本波形的波形参数的方法。
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。
