clock recovery

Clock recovery is a technique used in digital communication systems to synchronize a receiver's clock with the sender's clock. When data is transmitted electronically, it can arrive at slightly different times or with irregular timing. Clock recovery ensures the receiver accurately interprets the data by extracting timing information from the signal itself, often by analyzing the data pattern or using special circuits. This synchronization allows the receiver to correctly sample the incoming data bits, reducing errors and ensuring reliable communication. Essentially, clock recovery aligns both parties' timing so the data can be understood clearly and consistently.
