A novel method to develop a frequency synthesizer with wide frequency coverage, fast frequency switching speed, and low phase noise is proposed.

提出了一种宽相对覆盖、低相位噪声的捷变频频率合成方法。

More unusual, certainly at this price point, is the tweeter which is equipped with an aluminum phase plug, and ACTS as a waveguide to smooth response and further widen high frequency coverage.

更不寻常的当然是在此价位上，高音配备了一个铝制的相位平衡器，并且它起到了一个使波形平滑的作用，进一步加宽的高频范围。

It doesn't tell us about the quality of the test coverage, the severity of the bugs, or the frequency with which customers will actually hit them.

它没有告诉我们测试覆盖的质量，程序缺陷的严重性，或是客户将在实际中碰到它们的频率。

The mobile firm has made no secret of its desire to get its hands on lower-frequency spectrum, which can cover much larger areas and offers better indoor coverage than the high-frequency spectrum it currently owns.

They mistake increases in their own coverage of certain phenomenon for an increase in the frequency of the phenomenon itself.
