时间信号 meaning in Chinese
time code
time signal
timing signal
Examples
- Time signal station
时间信号站 - The key idea of the system is converting the two - dimensional image data to one - dimensional digital temporal signals by virtual - loops
其核心思想是通过视频虚拟线圈将二维的图像信号转化成一维的数字时间信号。 - These handheld instruments provide latitude , longitude and altitude by picking up timing signals from global positioning system satellites
这些手持式装置藉著接收全球定位系统的卫星时间信号，可以提供经度、纬度以及海拔高度。 - In the second part , we investigate the frequency analysis problem . the freque - ncy analysis problem is to determine the unknown frequency wj when values of x ( m ) ( observations ) are known
在第二章里讨论频率分析问题。频率分析问题研究的是通过一组已知的离散时间信号值x ( m )来决定未知频率_ j的近似值。 - First , how to conduct sample and quantification of continuous time signal which is prior condition of sdr is explored in detail , and the comparison and analysis of some sample modes are given in which band pass signal sampling theorem is most important . second , multi - sample rate signal processing which is an important basis of sdr is studied . emphasis are put on decimation and interpolation those are the most fundamental process and the realization of decimation and interpolation filter
在基于中频采样的软件无线电结构框架下，首先详细探讨了软件无线电的前提条件，即如何对连续时间信号进行采样量化，比较分析了几种采样的方式，其中最为重要的是带通信号采样定理；然后探讨了软件无线电的一个重要基础，即多采样率信号处理，重点讨论其最基本的两个过程抽取和内插以及抽取器和内插器的实现；接着介绍了结构简单、适用于一级抽取的cic滤波器和适用于做2倍抽取的半带滤波器；再次论文在总结了传统的调制解调基础上，结合软件无线电器件的特点，系统的探讨并实现了基于正交思想的am 、 fm 、 ask 、 fsk 、 bpsk 、 qpsk的正交调制解调算法。
