数字数据

We described the design of data acquisition circuit in ultrasonic imaging system.

介绍了数字超声成像系统中数据采集电路的设计方案和功能特性。

Beyond the "Desktop" metaphor of the current information platform, the digital earth will form a natural, immersible information environment.

处理和解释这些数据成为人们面临的巨大挑战。早在1992年，美国副总统戈尔从生态环境和全球气候变化的角度提出了数字地球的概念［1］。

It is more and more imminently pressive for the speed of data processing in underwater acoustic digital signal processing. Now Real-time digital signal processing has been an important part of sonar system.

在水声信号处理中，对数据处理速度的要求越来越迫切，实时数字信号处理已经成为声呐系统中的重要组成部分。

The system uses temperature and humidity sensor SHT11 and smoke sensor MQ-N5 to collect data. SHT11 is a digital sensor with highly integrated inner system and anti-jamming capacity, which makes the collected signal more precise. The integrated I2C bus interface is a sensor, which can directly connect with any type of microprocessor and microcontroller system, it is very simple and practical.

本系统采用温湿度传感器SHT11和烟雾传感器MQ-N5来采集数据，SHT11是个数字传感器，内部高度集成，抗干扰性能，使采集的信号更准确，集成的I2C总线接口能是传感器可直接通过I2C总线与任何类型的微处理器、微控制器系统连接，十分简单实用。

Digital watermarking , which is inserting copyright information into the data , has been proposed to solve the problem.

数字水印技术是一种将版权信息嵌入多媒体数据中的方法，已经被应用于解决这一问题。

It can provide effective protection for digital media forgery, authentication, security and intactness by embedding a special mark into multimedia data.

数字水印技术主要通过在媒体信息中嵌入标记信号，为媒体信息在防伪、防篡改、认证、保障数据安全和完整性等方面提供有效的技术手段。

ARINC429 bus is the transmission standard of digital bus in aviation electronic equipment, and now it is widely used in different kinds of aviation electronic equipments. So the effective, convenient and credible data transmission is an important premise to ensure resource sharing and information interfusion.

ARINC429总线是航空电子设备的数字总线传输标准，目前广泛应用于各种航空电子设备中，其有效、便捷、可靠的数据传输是保证设备之间资源共享和信息传输的重要前提。

Numbers are my friends, so the economic figures were something I could internalize.

数字是我的朋友，所以我可以将这些经济数据转化为自己的认识。

Data acquisition is to invert analogy signal to digital signal, and then send it to the computer.

数据采集部分主要是从模拟信号源中采集信号并将之转换为数字信号送计算机处理。

For example, you could have a data acquisition device that has both analog and digital IO capabilities.

例如，你可以有一个数据采集设备具有模拟和数字IO能力。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
