滤波器

Provides a 6dB-per-octave rolloff filter at 115Hz.

提供一个115赫兹时每八度6分贝低频上移器。

Contains symbols for VHF, UHF, and SHF circuit design, including capacitance measurers, nonreciprocal devices, modulators, phase shifters, field polarization devices, and filters.

包含用于甚高频、超高频和特高频电路设号，包括电容测量器、不可逆设备、调制器、移相器、场极化设备和器。

The high pass filter cuts the lowest frequencies. This cab be useful in rooms where low frecuencies are amplified and tend to be "boomy".

高通器可以去除最低频率，对低频被放大，容易形成嗡嗡声房间，非常有帮助。

After analysis and determination on harmonic wave from rectification units operation, and understood hazardness of harmonic wave, the design project of harness was put forward.

介绍了电化学工业整流装置产生谐种类,谐治理方法,器种类及特点,器方案选择。

This paper presents a new frequency domain deghosting method on the basis of analyzing both the ghost formation mechanism and its filter spectrum characteristics.

在分析了虚反射形成机制及器频谱特性基础上,提出了一种在频率域剔除地震鬼新方法。

Numerical simulation studies indicate that the adaptive filter is a powerful noise suppresser for correlated interferences, especially for those with amplitude changing and time delay.

数值模拟结果表明该器对于相关噪声，尤是有幅值变化和时间延迟情况，有很强抑制效果。

Finally, in the micropolis corners you can see ring resonators, which are a conventional (non photonic-crystal) way to achieve a resonant cavity for use in channel-drop filters, etcetera.

最后，在光子微域转角处，你可以看见环形谐振电路，这是用传统方式（非光子晶体方式）来表示用于器等谐振腔。

Ends of the tegular filters (10) are cut off crosswise to make the end surfaces respectively form inclined surfaces such that vertical sections of the tegular filters (10) are in a rough trapezoid.

瓦状器(10)端部被斜向切除以使端面分别形成斜面，从而瓦状器(10)垂直截面呈大致梯形。
