- 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;
- If this modulation frequency is present the output of the comparator will be low. 如果这是本调制频率的输出将是比较低。
- It is convenient to change the optical intensity of the sidebands by tuning the DC bias voltage while the microwave modulation frequency and power are fixed. 当微波调制频率及功率一定时,可方便地调节直流偏置电压来改变各阶光波的强度。
- Experimental data show that the intensity modulation depth increases with the bias current of LD.When the modulation frequency increases,the intensity modulation depth decreases. 实验数据表明,光强调制度随激光器偏置电流的增加而加深,随调制频率的升高而减小。
- The character of FSK spectrum is centrosymmetric, spectrum peaks spread with an interval of the modulation frequency, so the right frequency cannot be got by FFT spectrum. 移频信号的频谱特性是谱峰以新出现的边频频率为中心,以低频频率为间隔向两边展开,通过FFT谱分析不能得到精确的结果;
- The characters of this improved circuit are not only low phase noise and high stable carrier but also ideal AF modulation frequency response, excellent anti-vibration and temperature performance. 该电路不仅具有低的相噪、高稳定的载波,还具有理想的音频调制频响、优良的抗震动性能和温度性能。
- The change of the modulation frequency will change the corresponding frequency value of the protuberant part on the PSD curve, and at the same time the peak value of the protuberant part is changed. 当调制频率不同时,PSD曲线的突变部分会发生相应的频移,调制频率高则突变发生在空间频率较高的频段,同时PSD峰值不变。
- To solve the problem of sky-high modulation frequency requirement in MOG (Micro-Optical Gyroscope), a new double-frequency modulation technology based on triangular wave was proposed. 对微光学陀螺双频率调制中需要极高调制频率差的问题,提出了一种基于三角波的双频率调制技术。
- An advantage of resolution is they use simple setting only a cursor, measurable the modulation frequency of the radio system that cannot survey with common frequency tally or parasitism frequency. 分辨率的一个优点是他们只用简单的设置一个光标,就可测量用通俗频率计数器无法测量的无线电系统的调制频率或者寄生频率。
- Since outputs of the master laser are antiphase for direct modulation and external modulation, the fluctuations of similarity index with modulation frequency for the two lasers are contrary. 由于内部、外部调制引起主激光器的输出反相,两种调制方式下同步品质随调制频率的变化趋势也相反。
- The picture on the wall is crooked. 挂在墙壁上的画是歪的。
- I wouldn't sell that picture for all the world. 我无论如何也不卖那幅画。
- She laid the picture face downward on the table. 她把那幅画正面朝下放在桌上。
