查询词典 waveform synthesizer

A real-time DSO that could capture a single cycle of the same 12 GHz waveform would be prohibitively expensive.

可以在一个周期里捕获12GHz 波形的实时示波器会非常昂贵。

In practical communication systems, it is necessary to apply data equalizers to recover the original waveform from the distorted one.

在实际的通讯系统中需要以资料等化器来回复一个失真信号的原始波形，近来许多以类神经网路为基础的等化器设计被应用在严重失真的信号回复。

Moreover, second-winding current waveform of a current transformer is calculated under the transient current of the typical short-circuit fault by numerical method. The analysis shows that the relevant protection equipment may refuse to trip when the fault current is extra high. It will result in the maloperation of protective relays for loss of their selectivity, and cause other protective relays to operate beyond range, and extend the scope of shutdown of power supply.

在这些回路出口处发生相间直接短路等严重故障时，流过相应TA一次侧的故障电流可能达到TA额定工作电流的100倍以上，大大超过了保护用TA的10%误差容许倍数，将使TA严重饱和，从而影响相关的保护设备的动作性能，因此有必要对在这种特大电流作用下的TA的传变特性做一些探讨，以分析其对继电保护装置动作特性的影响及应采取的措施。

A very large value, often 1,000 micro farads or many times more, is needed to "smooth" the rectified waveform to "flat" DC.

这种电容通常是容量很大的，比如1000微法甚至再大很多倍。通过它才能得到平滑的直流电压。

The modulator (25) may also include an offset circuit (24) so that the modulated waveform includes a carrier frequency indicator.

所述调制器(25)还可以包括偏置电路(24)，使得调制波形包括载频指示符。

Also, by using a novel offset architecture, as opposed to completely overlapped architecture, for the differential transmission pair, a 33% reduction of thickness is achieved in the design of a miniaturized common-mode filter with multi-layer LTCC technology. In view of increasing need of high-speed clock and data circuits to control their skew problems, a design of LTCC delay line is then conducted. To improve the waveform distortion associated with the microstrip/stripline-type meander delay line, a miniaturized high-frequency 3-D delay line with grounded guard traces is introduced. By means of 3-D structure, the 233 ps delay time, which requires extra board space amounting to a factor of 2.34 by stripline type meander delay line, can be shrunk into an EIA 1206 form factor.

为因应高速时脉及高速线路的不断发展，用於控制讯号、时脉同步的延迟线路需求日益增加，接著讨论的题目便是应用低温共烧陶瓷制程技术设计多层的延迟线路元件，为了改善在微带线/带线型折线式延迟线路波形失真的问题，论文中提出以接地的防护线来设计小型化的三维多层延迟线路元件，比较应用带线型折线式延迟线路和应用三维架构设计的延迟线路元件，同样提供233 ps的延迟时间，多层架构设计之延迟线路可缩小至EIA 1206 的尺寸，省下2.34倍的电路板面积。

A digital signal-average experiment unit is home-built. By LabVIEW programming, distant students on the Internet are allowed to operate the laborartory equipment, obtain signal waveform and experiment data, and observe the real-time video capture of the laboratory equipment through a video camera, so the real experiment is conducted and accomplished remotely.

如氮气之类的载体通过管线20和阀22引入，与管线26相通，与气体样品混合。

But for the most part, knaves and parasites had the command of his fortune

然而支配他的家产的大多是恶棍和寄生虫。
