sinusoidal wave meaning in Chinese
正弦波
Examples
- The nonlinear wave shape degenerates to a sinusoidal wave .
非线性波形衰减成正弦波。 - Alignment fields consist of very low distortion sinusoidal waves
排队过程包含很低的扭曲的正弦波。 - Sinusoidal frequency estimation is the procedure which can estimate the frequency of sinusoidal waves in additive white gaussian noise through transform and calculation for signal ' s samples
正弦信号频率估计是指通过对信号采样值的计算和变换，估计出淹没于噪声中的信号的频率的过程。 - In this paper , when the global optimal theory and monte - carlo technique are applied , i transformed the maximum likelihood frequency estimation problem of sinusoidal waves from multidimensional grid search to a closed expression . this makes it easy to estimate the frequency through optimal calculation
本文即是从解决以上的问题入手，通过结合运用全局优化理论和monte - carlo技术，使多个正弦波的最大似然频率估计问题由多维格形搜索变成了一个闭合的表达式，从而可以通过优化计算来进行频率估计。 - The satss is an antenna pointing servo system with ultra - low speed and high accuracy , driven by a rare earth permanent magnet ( repm ) brushless dc torque motor . to reduce torque ripple , the repm brushless dc torque motor has a slotless armature , and uses sinusoidal wave driven technology
卫星天线跟踪伺服系统为超低速高精度天线指向控制系统，该系统使用稀土永磁式无刷直流力矩电机作为天线的驱动机构，为降低转矩脉动，电机采用无槽电枢结构设计，并使用正弦波驱动方式。
