**传真机原理详解：从传统到数字化转变** 一、传统传真机原理 传统传真机是通过电话线路发送和接收文本或图像的电子通信设备。以下是其基本原理详解： 1. 扫描与转换：原始文件（如纸张）通过扫描器转化为电子信号。扫描器通过光线和镜头的组合，将文字或图像转换成光信号。 2. 调制解调：光信号被转换为电信号后，通过一种叫做调制的过程将其转换成能够在电话线上传输的信号。这个过程涉及到将电信号进行频率和幅度的调整，以便于传输。 3. 传输：经过调制的信号通过电话线路传输到接收方的传真机。接收方的传真机则通过解码将这些信号还原成原始的电信号。 4. 打印或显示：接收方传真机内的打印机或显示屏接收到这些信号后，将其还原成原始文件的形式。如果是打印机，则会将图像或文字打印在纸上；如果是显示屏，则会显示出来。

二、数字化传真机原理 随着科技的发展，数字化传真机逐渐取代了传统传真机。数字化传真机利用了现代通信技术，其原理如下： 1. 扫描与编码：与传统的扫描过程类似，数字化传真机首先会将文件扫描并转换为电子图像或文档。然而，这里的转换会涉及更为复杂的编码技术，如JPEG或TIFF等格式的压缩编码。 2. 数据传输：数字化传真机将编码后的数据通过互联网或其他通信网络进行传输。与传统的电话线路不同，这需要更为稳定的网络连接和更先进的加密技术来确保数据的传输速度和安全性。 3. 解码与打印：接收方接收到数据后，会进行解码并还原为原始的电子图像或文档。然后，可以通过连接到计算机的打印机或其他设备进行打印，或者通过屏幕直接查看。 三、从传统到数字化的转变 随着互联网和通信技术的进步，数字化传真机逐渐取代了传统传真机，这种转变是必然的。传统的传真方式虽然使用简单，但在效率、成本、易用性和可维护性方面均有所欠缺。数字化则实现了文件的高速传输和保存，并增加了安全性、便利性和效率性。它不仅可以节省时间成本，还提高了传输质量和速度。 **Translation**: Detailed Explanation of Fax Machine Principles: Transition from Traditional to Digitalization I. Traditional Fax Machine Principles The traditional fax machine is an electronic communication device that sends and receives text or images through telephone lines. Here is a detailed explanation of its basic principles: 1. Scanning and Conversion: The original document (such as paper) is converted into electronic signals through a scanner. The scanner converts text or images into optical signals through a combination of light and lenses. 2. Modulation and Demodulation: After being converted into electrical signals, the optical signals are modulated into signals that can be transmitted over the telephone line. This process involves adjusting the frequency and amplitude of the electrical signals for transmission. 3. Transmission: The modulated signals are transmitted to the receiving end's fax machine through the telephone line. The receiving end's fax machine decodes these signals to restore the original electrical signals. 4. Printing or Display: After receiving the signals, the printer or display screen of the receiving end's fax machine restores them to the original document format. If it's a printer, it will print the image or text on paper; if it's a display screen, it will show it. II. Digital Fax Machine Principles With the development of technology, digital fax machines have gradually replaced traditional ones. The principles of digital fax machines use modern communication technologies, as follows: 1. Scanning and Encoding: Similar to the traditional scanning process, digital fax machines scan documents and convert them into electronic images or documents. However, this conversion involves more complex encoding techniques such as JPEG or TIFF compression encoding. 2. Data Transmission: Digital fax machines transmit encoded data through the Internet or other communication networks. Different from traditional telephone lines, this requires a more stable network connection and more advanced encryption techniques to ensure data transmission speed and security. 3. Decoding and Printing: After receiving the data, the receiving party decodes it and restores it to the original electronic image or document. Then it can be printed through a printer connected to a computer or viewed directly on a screen. III. Transition from Traditional to Digitalization With the advancement of Internet and communication technologies, digital fax machines have gradually replaced traditional ones, which is inevitable. Although traditional fax methods are simple to use, they have shortcomings in efficiency, cost, usability, and maintainability. Digitalization achieves faster file transmission and storage, as well as increased security, convenience, and efficiency. It not only saves time costs but
