The magnitude-frequency characteristics of the noisy signal is utilized in the algorithm and the denoising is realized by the use of characteristic bases. 该算法利用含噪信号在幅频特性上的特征，通过特征基来进行信号的去噪处理。
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。
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。

It means that Dr Schneider can tell whether or not the signal from any particular binding site is too noisy to be useful—in other words, whether it is a damaging mutation. ECONOMIST: How (and why) to find a needle in a haystack The
For voice the difference will be a clean completed call or a noisy dropped call, for data services the better the signal strength the higher the data rate you will obtain in both directions. FORBES: The iPhone 4 Antenna Unravelled
