数字信号

Data acquisition system is an important part in digital signal processing system.

数据采集系统是数字信号处理过程中不可缺少的重要部分。

In Chapter 4 windowed function of data signal processing is introduced and applied to addition theorem, which succeeds in solving the difficult problem: it has a bad result when recursive T-matrix is applied to calculate the wave scattering of electrically large objects and multiple objects in the excitation of TE wave.

在第四章中引入数字信号处理中的窗函数，成功解决了在入射波为TE波时，用递推T矩阵法计算电大尺寸物体或多个散射体时，精度不高的问题。

Digital signal in the transmission process, the additive noise, crosstalk between the code will have an error, and so on.

数字信号在传输过程中，加性噪声、码间串扰等都会产生误码。

The AC-DC-AC voltage source inverter main circuit and TMS320LF2407 are selected to form high performance alternating current excitation system of ASG in this dissertation after detail schemes argumentation.

本论文在详细方案论证的基础上选择了交－直－交电压型主电路和数字信号处理器TMS320LF2407构成高性能的异步化同步发电机交流励磁系统。

Meanwhile, the part of software has realized the function of the alternating electricity parameter analysis, the directing electricity parameter analysis and the demonstration, which is taking the sampled data in a sampling cycle as the examination object, and carrying on the analysis with the digital signal processing technology to the sampling data, and then programming with single chip.

软件部分则是以一周期内采集的数据为检测对象，用数字信号处理技术对采样的数据进行分析，用单片机进行编程，实现交流电参量和直流电参量分析及显示功能。

Will be collected analog data converters and digital signal to the computer, as well as in the single-chip display.

将采集到的模拟数据转换成为数字信号并传给电脑，还有在单片机上显示。

That's when the nation's broadcasters went from analog to digital signals.

因为那天正好是国家的播音员进行模拟到数字信号的切换的时间。

Modern Communication System has been switched from analog signals transmission to digital signals transmission.

在现代通信系统中，使用数字信号传输的优势越来越明显。

In digitizing analogue signals, the digital signal is corrupted by the noise due to the inherent noise of the sampler and the quantizing noise.

在这两个过程中，由于采样器固有噪声和采样脉冲抖动噪声以及量化噪声等因素的影响，采用量化后的数字信号中含百噪声。

Actually, in most cases DSPs are designed to replace the ON-line analogue ones.

其实，在大多数情况下数字信号处理器的设计，以取代在线模拟的。

I will endeavour to find you some assistance.

我尽力帮你找人帮忙。

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
