Digital Communication - Research Paper Example Digital communication is the transfer or transmission of data from point to another and it is generally encoded digitally and this form of communication was first emerged in 1920's but its presence was there since the establishment of general communication. Since its emergence new technologies have been seen in the world. Basically the history of digital communication revolves around the three basic networks, i.e. computer, telephone and Cable TV. T1 similarly, emerged in 1960's during the digital upheaval in the roots of the U.S telephone network. But now it is used irresistible for data broadcasting. It is due to the telephone companies that T1 exists in this world. Due to the continuous improvements in technology of Digital communication, new communication systems emerged as some of the major today's digital communication systems includes GSM, iDEN, CDMA and others. In general this research paper includes the history of digital communication and T1 and the main components included in this report is the description of digital communication and T1, its application. This report explains and emphasizes how different people contributed in this field and brought new revolutions and new technologies and how it is being used in the present situation. Digital CommunicaDigital Communication Digital Communication is also known as data transmission in which the data is physically transferred through a communication channel, i.e. point-to- point or point-to-multipoint. The data transmitted during this communication process are electro-magnetic signals such as microwave signals, electrical voltage signals or infra-red signals, while copper wires, optical fibers, wireless communication, storage media are the most common communication channels used. When data is being transmitted, it mostly uses digital messages which are originated from mostly a computer or a keyboard. Digital communication or data transmission is a sub field from data communications, and also has a strong background with telecommunications and electrical engineering. T1 T1 is also known as DS1, is a T-carrier signaling scheme which was developed by Bell Labs and is mainly used to transmit voice and data between different devices. It is mostly used in telecommunication departments in North America and Japan. T1 is defined as a mean that carries multiple voice and involves data conversion in a single line in a full duplex (transmission method that involves that transmits and receive the information at the same time) synchronous data transmission technique where the data is transmitted at an aggregate speed of 1.544 Mbps. The T1 circuit is made up of twenty four 8 bit channel, in whicj each cannel comprises of 64 kbits/s carrier circuits. History of Digital Communication Digital communication has been used since the advent of communication, when data was transmitted through non-electrical means such as optical and mechanical. The
