DIGITAL TRANSMISSION
DIGITAL TRANSMISSION * Data transmission and data reception is the transfer and reception of data over a point-to-point or point-to-multipoint communication channel. Examples of such channels are copper wires, optical fibers, wireless communication channels, storage media and computer buses. * Digital transmission is employed in order to achieve high reliability and because the cost of digital switching systems is much lower than the cost of analog systems. * For a computer to use the data, it must be in discrete digital form. Similar to data, signals can also be in analog and digital form. To transmit data digitally, it needs to be first converted to digital form. * Digital Transmission is the transmission of signals that vary discretely with time betw...
