加拿大代写论文之数字通信
数字通信意味着将指的通信，即使用在0和1的信息传输从点到点。从模拟系统，数字通信是完全不同的，因为它涉及到使用代码的“0”和“1”，形成一些系列的连续时间信号。在数字通信中的情况下，有使用的采样过程中，使得输入的输入被转换成离散的和数字化的系列，使这些编码输入数据可以容易地被发送。在接收机端，一旦这些编码数据被得到，它需要被转换成一些可以理解为用户符号。由于衰减，色散，低带宽，或噪声，失真，质量差，有一定的概率获得。因此，有一个很高的要求，以除去这样的噪声和不想要的东西，从所接收到的代码之前被转换为输出（1987年佩顿Z.皮布尔斯）。
如果在从数字通信方法的信息的传输，我们需要以下设定。我们可以看到从以下数字通信的过程中，有一个组合的数字通信和类似的通信。在这里，发射机，信道和接收器类似通信的对象。
加拿大代写论文之Digital Communication
Digital communication means digitations of communication, i.e. uses of 0 and 1 in transfer of information from point to point. A digital communication is completely different from analogous system as it involves continuous-time signals that use the codes of 0’s and 1’s to form some series. In case of digital communication, there is usage of process of sampling for the inputs so that the input is converted into discrete and digitized series so that these coded inputs can be transmitted easily. At the receiver end, once these coded data is obtained, it is needed to be converted into some understandable code for the user. There is some probability of getting distortion and bad quality due to attenuation, dispersion, low bandwidth, or noise. So there is a high requirement to remove such noise and unwanted things from the received codes before it is being converted to the output (Peyton Z. Peebles 1987).
For the transfer of information from digital communication method, we require the following setup. As we can see from the following process of digital communication, there is a combination of digital communication and the analogous communication.
Here the transmitter, channel and receiver are the objects of analogous communication.
