spectrum function meaning in Chinese
频谱函数
Examples
- Spread - spectrum function of spread - spectrum communication system
扩频通信中的扩频函数 - A filter whose transfer function is matched with the frequency spectrum function of input signal
其传递函数与输入信号的频谱函数相匹配的一种滤波器。 - And we utilize the relation of spectrum function and correlation function to give the way of estimating doppler spread width
进而通过matlab建立模型,验证了此方法,并对其中的几个参数进行了分析和讨论。 - For focus measures , frequency spectrum functions , gradient functions and entropy function are analyzed in detail
其次，本文从频谱函数、梯度函数、熵函数等方面详细分析了对焦深度法中常用的对焦评价函数。 - We revised frequency spectrum functions by using weighting factor - the distance between direct component and alternating component , and improved the acuity of focus measure curve
提出用交流分量到直流分量的距离作为加权因子对频谱评价函数进行改进，有效地提高了对焦评价曲线的灵敏度。
