Effects of some factors on the performance of our Kalman filter in discrimination of closely spaced overlapping signals were investigated. 针对ICP-AES中严重重叠谱线干扰的校正,研究了若干因素对Kalman滤波器性能的影响。
In this paper, a Haar wavelet filter used in joint transform correlator is applied to optical pattern discrimination, and correlation spectrum subtraction of reference images is used to weaken the zero order dc diffracted. 在联合变换相关器中应用Haar小波滤波器进行模式识别,并利用参考物自相关谱抽取的方法来削弱零级直流分量。
Two-dimensional ( 2-D) multirate systems and filter banks ( FBs) have been used widely in image compression, video compression, digital communication, computer vision and texture discrimination and classification, etc. 二维(Two-dimensional,2-D)多速率系统和滤波器组理论已被广泛应用于图像压缩、视频压缩、数字通信、计算机视觉和纹理识别与分类等领域。
This paper concentrates on conductive EMI noise Diagnosis and impedance matching of EMI filter Design. Experiments show that discrimination network is effective, and there is also a method to choose the correct component values for EMI filter. 通过实例证明,传导性电磁干扰噪声分离网络能对共模和差模噪声进行有效地诊断,为正确选用抑制噪声的EMI滤波器提供依据。
Through a large number of experiments and the Cadence circuit simulation, it verified that the signal SPD had filter discrimination. And under the impulse tests of surge current, it can effectively limit the residual voltage within the tolerance which the device can take. 通过大量的实验以及Cadence电路仿真,验证了该信号SPD具有较好的滤波功能,且在电涌电流冲击测试下能够有效地将残压限制在设备耐受的范围内。
