Line coding is the process of * 2 points Ensuring synchronization between transmitter and receiver in a communication system. Modulating carrier signals with message signals to transmit information. Mapping digital data bits into digital waveform for transmission over a communication channel. Converting analog signals into digital form for processing by digital systems. Encoding digital data into analog signals for transmission over communication channels.
