例句

The IF and its associated sidebands are up-converted to the microwave region by the mixer, microwave oscillator, and bandpass filter.

中频载波和它的边带由混频器，微波振荡器，带通滤波器上变频到微波范围。

The higher frequency sidebands would have less contribution to the fluctuation due to smaller amplitude overlapping.

高频的频率边带由于幅度交叠的部分较少，所以对强度起伏贡献较少。

With increase in defect severity, energy is distributed to the sidebands of the gear mesh frequency across supply line frequency.

与增加的缺损严重，能源是分配给边的齿轮啮合频率跨越供电线路的频率。

In this paper, operational principle of CWDM linear sidebands filtering demodulation was elaborated and, experimental verification was made.

本文阐述了CWDM边带特性解调方案工作原理，并对其可行性进行实验验证。

The high efficiency in bandwidth and high suppression to sidebands are very meaningful for wireless communications.

高带宽传输效率和高边带抑制水平对无线电通信有着重要的意义。

By this operation the spectrum of the signal is divided in two sidebands .

藉着这操作信号的光谱在二个边带中被分开。

If the desired sideband is the baseband , then the undedired sidebands are eliminated with a lowpass filter .

如果，所希望的边带是基本波带，那么不希望的边带，就要用低通滤波器消除。

Otherwise the undesired sidebands are removed with a bandpass .

否则，不希望的边带就跟带通一起移动。

When the LO has a rich harmonic content , an input signal at any sideband will be replicated to each of the sidebands at the output .

当LO含有许多谐波时，在任何边带的输入信号，将被复制到输出点的每个边带上。
