课程名称：电信基础 课程概述：本课程旨在为工程师和通信初学者提供基础知识，内容以阿拉伯语进行简明扼要的讲解，同时配备英文学术术语，以帮助学习者后续在互联网上和专业文献中阅读。该课程是首个以这种简化方式讲解通信基本原理的视频课程，避免了复杂的细节，主要涵盖信号、天线、微波和卫星等基础知识。 电信是通过各种技术在电线、无线、电光或其他电磁系统上传输信息。它的起源是在于人类希望在比人声能传播的更大距离上进行沟通，同时追求效率，因此排除了慢速的通信方式（如邮政邮件）。电信领域的传输介质经历了多个技术阶段，从视觉信号（如烟雾信号、信号旗、光学信号发送器等）到电缆和电磁辐射（包括光）。这些传输路径通常被划分为通信信道，使得多个并发的通信会话得以复用。 长期以来，电信技术不断发展，20世纪和21世纪的长距离通信通常涉及电气和电磁技术，如电报、电话、电视、传真、广播、微波传输、光纤以及通信卫星等。20世纪初，无线通信经历了一次革命，意大利发明家古列尔莫·马可尼在广播通信领域的开创性发展，使他赢得了1909年的诺贝尔物理学奖。 根据《无线电规例》，电信被定义为“通过电线、无线、电光或其他电磁系统传输、发射或接收符号、信号、文字、图像和声音或任何性质的信息。”这一定义与国际电信联盟（1992年日内瓦）宪章和公约附件中的定义完全一致。 课程将深入探讨上述主题，希望能受到学员的喜爱。
الكورس موجه إلى المهندسين والمبتدئين في علم الاتصالاتسنقوم بشرح مبادئ الاتصالات العامة بشكل مبسط جدا باللغة العربية مصحوب بالمصطلحات الأنجليزية لتمكنك من القراءة بعد ذلك على الانترنت وفي المراجع المتخصصة بالاتصالاتالشرح يعتبر الاول من نوعه كفيديو الذي يشرح هذه المبادئ بهذا الشكل المبسط ودن الدخول في التفاصيل المعقدةسنقوم بشرح أساسيات الأشارات والهوائيات والميكروويف والأقمار الصناعية وغيرهاأتمنى ان ينال أعجابكمTelecommunication is the transmission of information by various types of technologies over wire, radio, optical, or other electromagnetic systems.[1][2] It has its origin in the desire of humans for communication over a distance greater than that feasible with the human voice, but with a similar scale of expediency; thus, slow systems (such as postal mail) are excluded from the field.The transmission media in telecommunication have evolved through numerous stages of technology, from beacons and other visual signals (such as smoke signals, semaphore telegraphs, signal flags, and optical heliographs), to electrical cable and electromagnetic radiation, including light. Such transmission paths are often divided into communication channels, which afford the advantages of multiplexing multiple concurrent communication sessions. Telecommunication is often used in its plural form.Other examples of pre-modern long-distance communication included audio messages, such as coded drumbeats, lung-blown horns, and loud whistles. 20th- and 21st-century technologies for long-distance communication usually involve electrical and electromagnetic technologies, such as telegraph, telephone, television and teleprinter, networks, radio, microwave transmission, optical fiber, and communications satellites.A revolution in wireless communication began in the first decade of the 20th century with the pioneering developments in radio communications by Guglielmo Marconi, who won the Nobel Prize in Physics in 1909, and other notable pioneering inventors and developers in the field of electrical and electronic telecommunications. These included Charles Wheatstone and Samuel Morse (inventors of the telegraph), Antonio Meucci and Alexander Graham Bell (some of the inventors and developers of the telephone, see Invention of the telephone), Edwin Armstrong and Lee de Forest (inventors of radio), as well as Vladimir K. Zworykin, John Logie Baird and Philo Farnsworth (some of the inventors of television).According to Article 1.3 of the Radio Regulations (RR), telecommunication is defined as « Any transmission, emission or reception of signs, signals, writings, images and sounds or intelligence of any nature by wire, radio, optical, or other electromagnetic systems.» This definition is identical to those contained in the Annex to the Constitution and Convention of the International Telecommunication Union (Geneva, 1992).
