噪声抑制

At last, the paper bring forward the restrain measure for not same noise, anticline scatter noise and the temperature change.

最后对干涉型光纤陀螺的误差机理进行了研究，提出了对光纤非互易性噪声、背向散射噪声和温度变化的抑制措施。

Unless the sources of the noise and the antinoise coincide, the wave patterns will not overlap properly and the effect will be lost.

如果噪声和反噪声不同步，它们的波形将无法准确地叠加，从而失去抑制效应。

Compared to the experimental measurements, good agreement is obtained near threshold region. It is shown that the fluctuations of the fundamental and second harmonic light in the laser field decrease as the cavity decay constant increases.

研究结果表明，激光场基波和二次谐波的涨落随空腔衰减常数的增大而减小；当激光场中含有乘性噪声时，乘性噪声能增强基波的涨落，同时抑制二次谐波的涨落。

Under the basis of these, the lately widely used wavelet transform in DSP is used to wipe off the noise in the band of the signal frequency. Lastly, for its function of auto noise-resistance and double integral, the triple correlation is also used to improve the sensitivity of the receiver.

在此基础上，为了提高系统在低信噪比下的相关检测能力，采用了近来在信号处理中获得广泛应用的小波变换来去除信号频带内的噪声，并用三重相关对噪声的自动抑制作用和对信号的双重累积作用来提高接收机对回波信号的接收灵敏度。

Because the Hall probe circuit, magnetic-flux meter circuit and extension measurement circuit share the same A/D converter, but MAX110 only have two channel, so the system use CD4052. CD4052 is the analog switch controlled by microcomputer, which can switch the three input channels. The singles is passed to microcomputer after A/D converted.

所有与模拟电路有关的低频接口控制线都采用光电耦合器TPL521进行隔离，而频率较高采用6N137构成单片机相关外围器件的隔离，以便抑制数字电路的尖脉冲和其他噪声对模拟电路产生干扰，提高系统的信号噪声比。

Noise is suppressed in an input signal that carries a combination of noise and speech.

在携带噪声和语音的组合的输入信号中的噪声得到了抑制。

Based on the multi-resolution analysis of wavelet, it gives a multiresolution network to combine the noise insensitiveness ability of wavelet and edge enhancement ability of the Lateral Inhibition network.

第四：将小波变换抑制噪声的功能和侧抑制网络增强边框的功能有机结合，独立提出一种基于小波变换的多分辨率分析的侧抑制网络的改进方法。

Firstly, nonlinear diffusion filter was used to wipe of noise efficiently and kept the edge information of the image. Secondly, gradient calculation of pixel diagonal direction was considered in the calculation of neighborhood gradient amplitude which further repressed the impact of noise. Thirdly, using average interclass variance, the self-adaptively double thresholds for different images were calculated.

首先采用非线性扩散滤波减少了图像噪声，同时保持图像的边缘信息；在邻域梯度幅值计算中，考虑像素对角线方向的梯度，进一步抑制了噪声的影响；最后采用平均方差阈值法选取阈值，从而提高了对不同图像的自适应性。

Two algorithms breaks through the shortcoming of weighting value immobilizes in the traditional average filter algorithm, and it can characteristic adjust the weights from of data in the filter window, thus makes the weights from noise point is very small contributing to the output date.

两种算法突破了传统的均值算法中加权值固定不变的缺点，可以根据窗口内数据的特点来自适应的调整赋予每个采样点的权值，从而使受噪声污染的信号对输出的权值贡献非常小，而且通过对滤波因子的调整，使得对于脉冲噪声和高斯噪声均有良好的抑制作用。

Enhancement effect is obvious by combining de noising method with non linear gain method in the high frequency sub bands with worse resolution.

实验结果表明，本文提出的方法在有效的增强红外图像对比度的同时，又能很好的抑制红外图像中相关噪声、加性高斯白噪声和乘性噪声

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。

Designed by French fashion house Herm è s, this elegant uniform was manufactured in our home, Hong Kong, and was the first without a hat.
