Introduction
电子通信系统溶解通信能力的积极和消极影响。模拟或数字信号的系统,处理电路中电子传输,然后推导出的接收器。
电子通信系统是高度可靠和有效的错误最小化的程序。社交网络是最利用电子通信系统中休息。人们利用主要是分享他们的意见,意见分别通过社交媒体平台的援助。
What is an electronic communication system?
电子通讯称为沟通的那种认为,存储,传输或播放利用电子媒体如手机、电子邮件、视频和电脑。最近几天电子通讯提供了巨大效益的快速转换的数据(Saregar et al . 2019年)。
可以将数据发送给遥远的人在第二个电子媒体的协助下。< / p >

Figure 1: Electronic communication system
在这个数字化、通信与更广泛的范围和增强的可能,只能的协助下电子通信系统。很多转型逐渐发生在工作区中,领域和社会由于电子通讯系统(Pollacco et al . 2018年)。
通信的源由传输信息,如图像、图形、图片、声音、软件、地图和许多更多
Types of communication systems
通信系统分为不同类型,包括模拟和数字
模拟通信利用模拟信号传递的信息。利用模拟通信信号为正弦波。模拟提到的时变信号的地方的持续沟通交流与指定的两个或两个以上的来源。创建的消息来源一般是模拟的形式转换为数字类型,然后传播
数字通信系统利用数字信号传输的信息
Figure 2: Classifications of electronic communication system
电子通信系统分为不同的类型,包括短信、语音电话、电子邮件、社交媒体和许多更多。传播媒介逐渐转变和发展由于公众相互沟通的方式为不同的目的(Yazdeen et al . 2021年)。
电子通信系统使生活更加可行和他们更广泛的世界不同地方的人。
Uses of Electronic communication system
电子通信系统允许个人结合等多个媒体文本,图形,声音,视频和别人在一个单一的消息。
这些后果有意义的交互为特定受众的本质。窄播和广播代表能力提高很多通信市场的子集。
所认为的Markovićet al。(2020),电子通讯很互动,包括个人更积极的双向通信。电子通信系统广泛应用于各个领域,因为它使得一种新型的多对多的交互。许多组织和业务部门利用电子通信系统的设施如万维网(World Wide Web)个人交互工具来提高团队工作的有效性。
Terms used in Electronic communication systems
一些常见的术语大多是利用−在电子通信系统
−数据信号需要转换成电子一些数字类型,才能改变。一个信号表明,信息已变成数字类型
通信通道−沟通的渠道也是证明是一个信号转换的媒介接收或发送者。可以是简单的沟通渠道铜甚至卫星系统
换能器−传感器被称为设备,使一个能量形成另一个。它基本上是一个设备的电子通信系统将一个物理变量类型如力、压力和温度(罗et al . 2020年)。一个基本的例子,传感器是一种电话接收器
放大−放大的过程被称为加强信号振幅利用电子电路。信号的振幅之间的长度时低的接收方和发送方信号太大。在实现这个问题,放大的信号进行恢复力量。
