Master the art of Line Coding. Convert binary data into electrical signals for efficient, error-free communication.
In digital communication, we need to transmit binary data (1s and 0s) over a physical medium (wire, fiber, air). Raw binary data is often a long string of DC levels, which presents problems:
Line Coding is the solution. It is the process of converting binary data (bits) into a digital signal (voltage levels) suitable for transmission.
Where is the power concentrated? Avoiding low frequencies helps AC coupling.
Does the signal have enough transitions to allow the receiver to extract the clock?
Can the code detect errors? (e.g., bipolar coding prevents consecutive same-polarity pulses).
How resistant is the signal to noise? (e.g., higher levels usually mean better SNR).
Select a scheme below to see its definition and characteristics.
Input binary data or generate random streams to visualize encoding schemes in real-time.
Max 16 bits. Only 0s and 1s.
