The low power consumption digital true random source comprises a high speed random oscillator signalgenerator, an alternative oscillation stop control unit, a clock generator and a sampling unit.
它包括高速随机振荡信号发生器、交错停振控制单元、时钟发生器和采样单元。

In addition a digital signalgenerator was incorporated via a DDS chip AD9850 from Analog Devices inc, featuring accurate frequency preset, quick phase transformation and low phase noise.
The traditional PSS use the local signal such as the generator electromagnetism power or shaft speed as its input to restrain low frequency oscillation.
