例句

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

中頻載波和它的邊帶由混頻器，微波振蕩器，帶通濾波器上變頻到微波范圍。

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

高頻的頻率邊帶由于幅度交疊的部分較少，所以對強(qiáng)度起伏貢獻(xiàn)較少。

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

與增加的缺損嚴(yán)重，能源是分配給邊的齒輪嚙合頻率跨越供電線路的頻率。

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

高帶寬傳輸效率和高邊帶抑制水平對無線電通信有著重要的意義。

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

藉著這操作信號的光譜在二個邊帶中被分開。

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

如果，所希望的邊帶是基本波帶，那么不希望的邊帶，就要用低通濾波器消除。

Otherwise the undesired sidebands are removed with a bandpass .

否則，不希望的邊帶就跟帶通一起移動。
