加拿大论文代写之数字通信
介绍
的数字通信是较新的通信方式与长距离到短距离的数字介质的帮助。可以被定义为以0或1格式已被编码的信息的电子传输的数字通信。数字通信的主要目标是可信的在各种媒体上，它可以是网站，视频，音频，文字，动画多媒体通信的创造力。数字通信是比较流行的，在世界上所有的地方。这就是为什么，这是基础和最需要的技能和成长的职业生涯从。人们使自己的职业生涯，在这一领域有很大的需求和参与人的各项任务，如构思，生产，交付，接收此类通讯的一部分，他们的任务（AP克拉克1983年）。
类似通信，数字通信是完全不同的。的信号以类似于通信的情况下，使用连续时间信号，可采取任何实际价值。此信号接收时，总是产生不同特性的输出。此外，类似的信号可以被扭曲，由于许多问题，如衰减，色散，低带宽，或噪音的质量也不是那么好。
因此，人们越来越多地使用数字通信，而不是类似的沟通，有效和高效的信息传输从一个点到另一个。有很多媒介的数字通信，如铜线，光纤，如Wi-Fi，蓝牙等无线通信介质的信息被发送（John等人，2004年）。
加拿大论文代写之DIGITAL COMMUNICATION
Introduction
The digital communication is newer way of communication with the help of digital mediums over long distances to short distances. The digital communication can be defined as electronic transmission of information that has been encoded in 0 or 1 format. The main objective of digital communication is the creativity of credible communications in various media which can be it websites, video, audio, text, or animated multimedia. Digital communication is more popular and used in the world in all places. This is the reason for which this is becoming base and most required skill for making and growing from the view of career. People are making their career in this field as there is great demand and the involvement of people in various tasks like conceptualizing, producing, delivering, and receiving such communications as a part of their tasks (A. P. Clark 1983).
Digital communication is completely different from Analogous communication. In case of analogous communication, the signal uses continuous time signals which can take any real value. This signal is when received, always produces an output of varying characteristics. Also the analogous signal can get distorted and the quality is not so good due to many problems like attenuation, dispersion, low bandwidth, or noise.
Therefore, people are using more digital communication rather than analogous communication for effective and efficient transfer of information from one point to another. There are many mediums for such digital communication like copper wires, optical fibers, wireless communication mediums like Wi-Fi, Bluetooth, etc. by which the information is being transmitted (John et. al 2004).
