The sampled data was transferred from the data acquisition box to the computer through the enhanced parallel port ( EPP). 采用增强型并口(EPP)实现计算机与外置数据采集模块的高速数据传输。
Described in this paper is a sampled data approach adopted to derive the expressions of the probability density function, detection and false alarm probabilities, which are then verified by computer simulations. 本文采用一种抽样数据方法导出了这个概率密度函数表达式及检测概率和虚警概率表达式,并通过了计算机仿真验证。
When flying objects with high speed pass through the laser screen, change of light flux is transformed into electronic signal and sampled by data sampling card and processed by computer. 当高速飞行物体穿越激光光幕时,光通量的变化被转变为电信号并采集到计算机进行数据处理。
Video signal was sampled and compressed by the image processing part of system, and then the video data was stored by the image storing part of system, computer read out the compressed image data stored on CF card and replayed with on the computer. 图像处理部分完成视频信号的采集、A/D转换、压缩编码,数据存储部分完成视频编码数据的存储,计算机读出保存在CF卡上的视频文件,实现图像播放。
The physiological signals are sampled by the signal sampling system. It includes sensors, signal conditioning module ( amplifier, pre-process module), data acquisition card and computer. 信号首先通过自行设计的信号采集系统进行采集,信号采集系统包括:传感器、信号调理模块(放大器、预处理器)、数据采集卡、计算机等。
