查询词典 signal clock

By utilizing the cross gain modulation effect and the period 1 oscillation harmonic frequency locked in an optically injected semiconductor laser , we can extract the wavelength conversional individual channel optical clock from the optical time division multiplexing OTDM signal .

光注入半导体激光器会产生非线性单周期振荡特性，利用交叉增益调制效应及对单周期振荡的微波锁频效应，可从光时分复用信号中提取出波长转换的分路光时钟。

First, mathematical foundation of synchronization, i.e. the theory of parameter estimation is introduced. Then, DA/DD or NDA timing synchronization methods based on the ML estimation of timing parameter are presented. They are all widely applied in actual digital communication systems. Interpolation theory in digital signal processing has application in timing synchronization, which makes the sampling clock independent of the timing control so that timing adjustment is realized completely through digital disposal. The issue of interpolation in timing synchronization is discussed.

首先，介绍了定时同步实现的数学基础，即信号参数估计理论；从定时参数的最大似然估计出发，介绍了基于数据辅助的定时同步方法和基于非数据辅助的定时同步方法，他们在实际的数字通信系统中均有广泛应用；论文探讨了数字信号处理中插值理论在定时同步中的应用，它使得接收端的采样时钟独立于定时控制，定时调整完全通过数字处理方法得以实现。

The speed with which your microcomputer executes programs will vary linearly with the speed of your clock signal.

你的微型计算机执行程序的速度将与你的时钟信号的速度成线性关系。

This reduces the impact of a short circuit and assures that the bus does not conduct current through the aircraft. A Manchester code is used to present both clock and data on the same wire pair and to eliminate any DC component in the signal (which cannot pass the transformers). The bit rate is 1.0 megabit per second (1 bit = 1 μs).

该结构可以削弱短路对总线的影响并保证总线不会传导在航空器中流转的电流。1553总线用曼彻斯特码表示导线对上的时钟信号和数据信号，这可以去除信号中的直流成分，因为直流成分不能通过变压器。1553总线的波特率是1兆位每秒，即每微秒传输一位信号。

When metastability occurs the clock-to-out time can be extended beyond the register's nominal tCO time. The additional time beyond the tCO time for the output signal to settle to a known state is known as the settling time. The tMET of a synchronization register chain is the sum of all output slacks of the registers in the chain.

对于这段话，我的理解是： tMET 时间和 tCO 时间之和就是异步时钟域的亚稳态时间，如果这个时间大于目的时钟域的同步寄存器链的时序余量（大概是时钟周期减去它的建立时间和保持时间之和吧），那么这时候系统采到的信号一定是亚稳态。

Light is the primary signal that synchronizes, or entrains, the organismal clock to exactly match the environment.

光是最原始的同步调节信号，使生物体的"时钟"与环境同步或者迫使同步。

You can specify a particular phase for the generated clock signal, and also a permissable tolerance (as some devices may be able to get near to, but not exactly, the frequency you require).

您可以定义生成的时钟信号的一个特地相位，或者一个可接受的误差范围（因为一些器件可能不能输出您需要的频率的精确值，只能输出接近的频率值）。

The disadvantage of such a clock grid resides in its problematical generation, in particular when video recorders are used as signal source.

这样的时钟栅的缺点在于它不能预知的产生，尤其是当录像机用作为信号源时。

However, the CMOS image sensors can provide stronger anti-radiation capacity than CCD as well as Single Chip Integrating with image sensors array, drive and control circuit, signal processing circuit, A/D conversion circuit and Completely Digital Interface Circuit. The CMOS image sensors also possess high quantum efficiency, wide spectral response, good response uniformity, low supply voltage and low request of clock.
