quasi-synchronization (plesiochronous). The Manchester code allows the receiver to easily extract the clock information from the received bitstream, making it easy to synchronize bits. In the asynchronous communication with the frame as the transmitting unit, the receiver usually uses the method of extracting the clock information from the received bit stream to realize the bit synchronization.In the character-based asynchronous communication, because each character only
