Which encoding technique attempts to solve the loss of synchronization due to long string of os?

The encoding technique that addresses the loss of synchronization due to long runs of zeros (os) is called Run-Length Encoding (RLE). In RLE, sequences of repeated symbols are stored as a single data value and count, which helps maintain synchronization by breaking long strings of zeros into shorter representations. Additionally, techniques like Bipolar Encoding or Alternate Mark Inversion (AMI) can be used to ensure that there are enough transitions in the signal to maintain synchronization, even during long sequences of zeros.
