filter characteristic meaning in Chinese
滤波器特性曲线
Examples
- Pll has the excellent narrow - band - tracking - filtering characteristic . in this scheme , we combine the merits of dds and pll
该方案是将dds的高分辨率、高精确度、频率变化易于控制的优点与pll良好的窄带跟踪性能相结合。 - We simulate other structures using the commercial software cst microwave studio , we get the tendency of the change , better filtering characteristics and we gain some useful conclusions
利用电磁仿真软件cstmicrowavestudio对其他基片集成波导结构进行仿真,得出其特点和变化趋势,得到了较好的带通滤波特性,得出了一些有用的结论。 - Median filtering is chosen to modify the fuzzy edge by using the smoothing arithmetic , sobel operator is used to detect edge because of its filtering characteristic . image is changed from gray - scale to two - valued according to the threshold which is automaticly selected by otsu
选用中值滤波减小平滑算法导致的边缘模糊;利用有滤波特性的sobel算子进行边缘检测;使用最大类间方差自动确定阈值,将灰度图像转化为二值图像。 - On the base of a systematical analysis about the theory of mathematical morphology and neural network , we present that the two methods have many complementary aspects : mathematical morphology has good filtering characteristic , but has not good adaptability and study ability from samples ; neural network has outstanding properties of self - organizing and self - adapting , but has not good filtering characteristic of mathematical morphology
本文在分析了数学形态学理论和神经网络理论的基础上，指出了两者在信息处理中具有很强的互补性：数学形态学具有良好的滤波特性，但适应性差，不具备从图像样本中进行学习的能力；神经网络具有很强的自组织和自适应性，却没有数学形态学良好的滤波性能。 - This paper begins with an overview of the fundamentals of adaptive antennas . the correspondence between a spatial filter and the fir filter is illustrated , and the spatial filter characteristic of adaptive antennas is investigated by dmi and ls - drmtcma algorithms . the discrete - time transmission model of synchronous cdma systems with antenna arrays is also developed
本文首先对自适应天线的基本原理进行了简要介绍，建立了阵列接收的同步cdma系统离散时间传播模型，并论述了空域滤波和时域fir滤波器的类比性，用dmi和ls ? drmtcam算法仿真了自适应天线空间滤波性能。
