将噪声添加到海拔和湿度图会导致在区域过度附近产生“抖动”。使用噪声在坐标附近采样会扭曲形状的边缘。
Adding noise to the elevation and moisture will produce "dithering" in the zones near transitions. Sampling nearby points using noise will distort the shapes of the boundaries.
随后，详细讨论了高速数据采集系统中抖动对数据采集系统信噪比的影响和偏移对正交采样一致性所产生的影响。
Then, we discuss jitter 's influence on Signal-to-Noise Ratio of data acquisition system and skew' s influence on consistency of orthogonal sampling of high speed acquisition system in detail.
不过，从低采样率抖动仍然存在。
抖动-在阴影边界应用采样，相同地，通过OS A按钮在物体边界应用反走样。
Dither? Applies a sampling over the borders of the shadows, quite the same way anti-aliasing is applied by the OSA button on the borders of an object.
相位抖动：指的是反馈时钟和参考时钟之间上升沿差异与多次随机采样的平均偏移之间的差。
Phase Jitter: refers to the deviation of the FBKCLK rising edge to the REFCLK rising edge with respect to the average offset in a random sample of cycles.
周期抖动：指的是信号的周期时间的随机采样与理想周期之间的差异。
Period Jitter: refers to the deviation in cycle time of a signal with respect to the ideal period over a random sample of cycles.
该系统采用了片同步技术实现了采样后高速数字信号的可靠锁存，采用高精度的时钟管理芯片和设计合理的时钟路径对时钟抖动做了严格控制。
The Chip-Sync technology has been used to ensure the latch of high-speed signal, and we use high accuracy clock management chips and design reasonable clock way to strict control the clock jitter.
随着采样频率和A/D变换器位数的增加，时钟抖动和相位噪声对数据采集系统性能的影响更加显著。
The effect of clock jitter and phase noise on data acquisition system performance is more profound as the increase of sampling frequency and the bit of A/D converter.
