signal fluctuation

As the variations of the signal frequency, the real number of samples in one cycle changes with the fluctuation of signal frequency which will lead to sampling synchronous deviation.

然而由于电网频率的波动，实际上一个周期内的采样点数N是随频率的变化而变化的，因此必然存在同步偏差，影响测量精度。

A Crankshaft Fluctuation Sensor ( CKF) is located near the bottom of the timing cover where it generates a signal as the crankshaft timing chain sprocket rotates past it.

曲轴位置传感器安装在定时器壳底部附近，产生一个曲轴定时链轮齿通过的信号。

Intensity fluctuation of any or all components of a received signal.

接收信号的部分或所有成分的强度起伏波动.

Generally, the friction differential pressure fluctuation signal or throttle differential pressure fluctuation signal was used to analyze the property of Gas-liquid two-phase flow.

以往对差压波动信号的分析，通常是指平行于流向测得的管道的沿程压力损失或节流装置产生的压力差。

The first task of applying deterministic chaos theory to studying the dynamics of fluidized bed from the time series of pressure fluctuation is the computation of delay time of reconstructed phase space. This paper studies the influence of periodic and stochastic signal on the computation.

应用混沌理论从流化床压力波动时间序列来研究流化床动力学行为的首要任务就是确定重构相空间滞时。
