In addition a digital signal generator was incorporated via a DDS chip AD9850 from Analog Devices inc, featuring accurate frequency preset, quick phase transformation and low phase noise.
另外还采用AD公司DDS器件ad9850实现了一种频率可控制、相位变化快、相位噪声低的DDS信号源。
The traditional PSS use the local signal such as the generator electromagnetism power or shaft speed as its input to restrain low frequency oscillation.
传统的PSS使用本地可测量的发电机电磁功率、转速等作为输入信号以抑制低频振荡。
The realization of the project is mainly composed of two parts. The first part is low frequency signal generator based on DDS, and the second part is high frequency signal synthesizer.
该方案的实现主要包括两大部分，其一是低频dds信号产生部分，其二是高频信号合成部分。
