查询词典 band filter

The paper employs the CF band pass filter to measure the cross-correlation coefficient and the leading / lagging relationship between credit variables and the economic growth rate. The result shows that the cyclical fluctuation of medium- and long-term loans and construction loans is in advance of the economic growth, and the cyclical fluctuation of industrial loans and commercial loans is relatively consistent with that of the economic growth.

The main points of this thesis are as follows: It is presented that the key issue to constructing of the orthonormal wavelet on the basis of multiresolution analysis theory is to design the wavelet bases which can be used to decompose the signal into a two-band form, while the construction of wavelet bases is equivalent to designing a filter bank with perfect or nearly perfect property restricted by regularity.

论文工作在以下几个方面取得了进展：提出用多尺度分析理论构造正交小波，最终可归结为构造能进行两带分解的小波基，而小波基的构造又等价于在附加正则性条件约束下，设计一个完全恢复和近似完全恢复的滤波器组。

Output of each filter reflects quantity of signal at that transmission band.

率不同的带通滤波器实现，各个滤波器的输出反映了信号在该通频带内的量值。

Besides, the lasing linewidth of the EDFL output becomes narrower by simply inserting an tiny air-gap between the FC/PC connectors of fiber patch cord, which functions as a intra-cavity Fabry-Perot filter in the cost-effective L-band EDFL system.

此外，我们还在环腔内光纤跳接线连接处产生一微小空隙，如同在环腔内加入一法布里裴洛滤波器，可使得雷射的线宽变的更窄。

Since the output signal from fringing field dielectrometry sensors under a low frequency driving voltage are very low, the shield-drive, signal buffer and band-pass filter are adopted to improve SNR. With the signal gain and phase angle from a transform circuit, the complex permittivity of pressboard are obtained.

鉴于边缘场电容式传感器在低频正弦驱动信号作用下输出的感应信号非常微弱，调理电路采用驱动屏蔽方式进行测量信号缓冲，用带阻滤波器提高信噪比，并利用相应的变换电路求出电容系统的相位角和幅值增益，从而得到绝缘纸板的复介电常数。

By fusing the IKONOS multi-band and pan image using several image fusion algorithms(IHS transform, PC transform, Gram-Schmidt transform and smoothing filter-based intensity modulation) and assessing the fusion image, indicates that qualitative comparison is too subjective, although many methods are provided for assessment when using quantitative methods, more bands and more methods should be used for their limitations, spectral curve comparison was the best method for appraising the result, spectral angle and geometry distance was introduced to appraise the spectral curve.

以IKONOS影像为数据源，对IHS、PC，Gram-Schmidt和基于亮度调节的平滑滤波四种融合算法进行融合处理，对其结果进行了评价。结果表明，定性比较主观性较强，定量比较方法虽多，但大都有一定的局限性，不同谱段的计算结果总有些差异。因此，定量评价时应该多选一些波段与评价方法才能获得比较客观的评价结果。光谱曲线的比较不失为一种比较好的方法，在对光谱曲线进行比较时本文引入了光谱角度和几何距离两种方法进行定量的比较。

The modulated signals are added up in a summator 120 to form a real signal, which is filtered by a RF filter 122 for attenuating out-of-band noise and spurious interference.

在加法器120中将调制的信号相加形成实信号，该信号通过RF滤波器122滤波，以衰减带外噪声和伪干扰。

The new function introduces a frequency sub-band threshold, supposing that the component value below than the threshold is noise, then filter it.

经过大量的实验，证明提出的方法具有单峰性好、灵敏度高等优点，特别是在抗噪声性能方面有很大提高。
