Clock recovery is a process used in digital communication systems to extract timing information from a received signal. This timing information is crucial for accurately interpreting the data bits transmitted over a channel. Without proper clock recovery, the receiver may misalign with the sender's timing, leading to errors in data interpretation. The clock recovery process typically involves analyzing the incoming signal to identify patterns or transitions that indicate when data bits start and end. Techniques such as phase-locked loops (PLLs) or digital signal processing (DSP) algorithms are often employed to synchronize the receiver's clock with the sender's clock, ensuring reliable data communication.
