In many cases, the digitized signal is passed through a source encoder, which employs a number of formulas to reduce redundant binary information. 32) In message switching system, an incoming message gets ____ especially if the required route is busy. Data transmitted in the form of electrical signals known as carrier waves, which are modulated into analog or digital signals to transmit information. Software This controls the Computer programs. The network can cover towns and cities of 50KMs or less. Telecommunications: Connecting the World 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.
