Therefore , the subject is to study the design theory and engineering realization of the low phase-noise phase locked source in microwave band.
在这样的背景下，本课题对低相位噪声微波锁相源的设计理论和工程实践进行了研究。
The analyses of frequency characteristic of the system demonstrate that the noise in effective frequency band is eliminated and the phase of the system is approximately linear.
并对系统的频率特性进行了分析，表明基于该技术的微加速度计系统在工作频段内噪声能够得到有效的消除，且具有近似的线性相位。
