What is bit destuffing?

Bit destuffing is a process used in data communication where extra bits that were added during bit stuffing are removed to restore the original data stream. Bit stuffing is often employed to prevent misinterpretation of data frames, particularly when specific bit patterns, such as flags, need to be avoided in the payload. By identifying and removing these extra bits, the receiver can accurately reconstruct the intended message. This technique is commonly used in protocols like HDLC and other transmission systems.
