noise signal generator

基本解释

The virtual signal generator can generate sine wave, triangle wave, square wave, sawtooth wave and other standard signal. It also can add some noise to those signal.
虚拟信号发生器模块能够产生正弦波、三角波、方波、锯齿波等标准信号，并且可以叠加各种干扰噪声；
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。
Agilent Technologies Inc. (NYSE: A) today introduced the industry's first pulse function arbitrary noise generator, which provides superior signal quality combined with versatile waveforms.
安捷伦科技有限公司（NYSE： A）宣布推出行业上第一个脉冲函数任意噪声发生器，提供结合多种波形的高质量信号。
