216AB61 模拟输入板

输入输出(input/output, /O)，读作"eye-oh” ，描述的是在计算机上输入输出数据的操作系统、程序或设备。-般的输入 输出设备有打印机、硬盘、键盘和鼠标。实际上，有些设备只有输入功能，如键盘和鼠标;有些设备只有输出功能，如打印机;还有些设备具有输入输出2种功能,如硬盘、磁碟和可写性只读光盘(CD-ROM)。

S端子也就是Separate Video,而"Separate" 的中文意思就是“分离”。它是在AV接口的基础上将色度信号C和亮度信号Y进行分离,再分别以不

同的通道进行传输，减少影像传输过程中的“分离”、“合成”的过程，减少转化过程中的损失，以得到最佳的显示效果。但S-Video仍要将两路色

差信号混合为-路色度信号C进行传输，然后再在显示设备内解码进行处理,这样多少仍会带来定信号损失而产生失真(这种失真很小)，且由

于混合导致色度信号的带宽也有一定的限制。 S-Video虽不是 最好的,但考虑到目前的市场状况和综合成本等其它因素，它还是应用最普遍的视频接

输入输出设备(I0设备)，是数据处理 系统的关键外部设备之一， 可以和计算机本体进行交互使用。如:键盘、写字板、麦克风、音响、示器

等。因此输入输出设备起了人与机器之间进行联系的作用。

Input/output (/O), Pronounced 'eye oh', it describes the operating system, program, or device that inputs and outputs data on a computer. Common input and output devices include printers, hard drives, keyboards, and mice. In fact, some devices only have input functions, such as keyboards and mice; some devices only have output functions, such as printers; and some devices have input and output functions, such as hard drives, magnetic disks, and writable read-only discs (CDs).

The S terminal is also known as' Separate Video ', and the Chinese meaning of' Separate 'is' separate'. It separates the chromaticity signal C and brightness signal Y based on the AV interface, and then uses

The same channel is used for transmission to reduce the process of "separation" and "synthesis" during image transmission, reduce losses during conversion, and achieve the best display effect. But S-Video still needs to combine the two colors

The difference signal is mixed into a chromaticity signal C for transmission, and then decoded and processed in the display device. This will still result in a certain amount of signal loss and distortion (which is very small), and

There are also certain limitations on the bandwidth of chromaticity signals caused by mixing. Although S-Video is not the best, considering other factors such as current market conditions and comprehensive costs, it is still the most commonly used video connector

Input and output devices (I0 devices) are one of the key external devices in data processing systems, which can interact with the computer itself. For example: keyboard, tablet, microphone, audio system, display

Etc. Therefore, input and output devices play a role in connecting people and machines.
