- high modulation index 高调制指数
- As has been already demonstrated, the modulation index defines the number of partials in the spectrum. 由大多数声学设备产生的分音振幅在声音持续其间变化。
- Frequency modulation offers an effective parameter for spectral evolution: the modulation index (i). 能够控制声音的时变频谱要素对声音合成来说是至关重要的。
- But the mechanism of cold cathode penning discharge results in high modulation ratio of ion current derived from the source, and lowers the quality of current. 但是由于冷阴极放电的限制,其引出束流的调制度过大,束流不稳定,这降低了离子束流的品质。
- At the same time, the RPWM spectrums under different modulation index were compared to expose the weakness of RPWM. 对不同幅度调制比下的RPWM波频谱进行比较,RPWM对幅度调制比要求较高。
- The modulation index can be increased by using distorted wave forms that contain only triplen (multiples of three) harmonics. 通过使用只含有三次谐波的波形作为载波可以提高这个调节指数。
- Note, however, that by linearly increasing the modulation index the instrument does not necessarily increase the power of high-order sidebands linearly. 频谱的这种短暂变化不总是能被清晰地听到。
- The main purpose is to study further in the constant envelope and Quasi-constant envelope modulations with high modulation efficiency. 主要研究适合深空信道传输的具有恒定或准恒定包络的高效数字调制方式与直接序列扩频相结合的组合调制解调方式。
- And higher modulation frequency can be achieved with small current aperture and adequate spontaneous emission factor. 通过减小VCSEL电流孔径、适当增大自发辐射因子可以实现比边发射器件高几倍的传输速率;

- Abstract:In this paper, a novel optical fiber type travelingwave modulator with high modulating characteristics is introduced. 摘要:文中提出新型的能提高调制器调制特性的光纤型行波调制器。
- An efficient Sphere Decoding (SD) algorithm is proposed for uncoded Multi-Input Multi-Output (MIMO) systems with a large number of antennas and higher modulation constellations. 该文针对无编码的多输入多输出无线通信系统中的最大似然检测接收机在发端天线数较多、调制阶数较高时计算复杂度过高的问题,提出了一种低复杂度的球形译码算法。

- She skirted round the problem of the high cost. 她避而不谈巨额费用问题。
- Men and birds are fain of climbing high. 不论人还是鸟都愿意往高处攀。
- The bird sang high and clearly in the tree. 鸟儿在树上清脆地高歌。
- Goods of high quality are few and far between these days. 质地精美上乘的物品现在不多见。
- The medieval town was fortified with a high wall and a deep moat. 这座中世纪的城市周围建有城墙和护城河。
- In the R-FOG based on the phase modulation spectroscopy technique,not only the optical power difference between the clockwise(CW) and counterclockwise(CCW) light waves induces the bias drift,but also the two different modulation indexes do. 基于调相谱检测技术的谐振式光纤陀螺系统中,除顺时针(CW)和逆时针(CCW)光路传播的光强不均匀会引入非互易相位差,使系统出现零漂外,顺时针和逆时针光路的调制系数也会引入系统零漂。
- I set a high value on his advice. 我认为他的忠告很有价值。
