1·In the process of signal transmission, noisy signals interfere with normal signals unavoidably.

在信号的传输过程中，噪音信号不可避免地会干扰正常信号。

2·On the basis, the characteristics called the ICA Energy (ICAE) and the Filtered ICAE (FICAE) are used for the noisy signal endpoint detection.

在此基础上提出了IC A能量(ICAE)和滤波icae (FICAE)特征来进行端点检测。

3·Wavelet soft-threshold de-noising method was applied to preprocess the noisy signal, and the noise interference in disturbance detection was reduced to a great extent.

采用小波软阈值去噪方法对信号噪声进行预处理，很大程度地减小了噪声对扰动检测的干扰。

4·In practice, the signal derived in this way would be useless, since each differentiation exaggerates any errors present, and so a double differentiation would inevitably produce a very noisy signal.

在实践中，得出的信号，这样是没有用的，因为每个分化夸大目前任何错误，然后双重差异，必然产生非常嘈杂的信号。

5·The first was to come up with a pre-agreed physical signal for Cara's children to react to when they got too noisy and started fighting.

第一种方法是为孩子们设计一个预先约定的动作信号，当他们吵得太凶或者开始打起来的时候用作回应。

6·Accelerometer readings can be jerky and noisy. Applying low-pass filtering on the signal allows you to smooth it and get rid of high frequency noise.

加速度传感器数值可能被颠簸和噪音影响。应用低通过滤器在信号上可以是它平滑，并摆脱高频噪音的干扰。

7·I wasn't able to copy my signal report because the band was very noisy.

因为这个波段噪声非常大，所以没有抄上给我的信号报告。

8·To estimate signal frequency and amplitude exactly under noisy circumstances, the excellent property of all-phase DFT restraining spectral leakage is mathematically proved.

为精确估计噪声环境中的信号频率和幅值，数学证明了全相位DFT优良的抑制频谱泄漏的性质。

9·An adaptive line enhancer based on the above notch filter extracts the fundamental frequency signal from noisy data.

采用自适应谱线增强器从含有噪声的数据中提取出基频信号。

10·Multiresolution support for lowpass filtering is introduced according to different property of wavelet transform for signal and noisy at different scale.

依据信号与噪声的小波变换在不同分辨率下呈现不同特性的特点，提出了多分辨率支集图像低通滤波方法。
