The analog tape can be converted to digital magnetic tape by using an A/ D converter, and then data processing can be done on computer. 通过模/数转换器,把模拟磁带转录成数字磁带,可以在电子计算机上进行各种数字处理。
A high-speed data acquisition system is designed and realized in this paper for electronic cabin signal group acquisition, including the analog input, signal adjustment, A/ D conversion, digital data transfer and storage and computer interface etc. 设计并实现了一种基于PCI总线的高速数据采集系统,主要包括模拟输入、信号调理、模数转换、数据传输存储以及计算机接口等部分。
Manage system of digital microscope video and image is such kind of system that taking digital computer capture technic into analog signal from camara and converting microscope video and image to digital data that computer system knows. 数字手术图像管理系统是:手术显微镜中的图像,由摄像机的模拟信号通过视频压缩技术,硬件芯片直接压缩为文件,保存到计算机中。
In the fields of modern electronic measurement, communication systems, radar and electronic countermeasures etc, it is very often to sample and storage to the broadband analog signal, for data processing in the computer. 在现代电子测量、通信系统、雷达、电子对抗等领域,经常涉及对宽带模拟信号进行数据采集和存储,以便计算机进行数据处理。
Specifically, it designs the transmission interface and driver of the data acquisition card, which turns the analog signals into digital signals and transmits data to the digital receiver of the computer. 具体地说,是设计数据采集卡的传输接口和驱动程序。
