Abstract
In one aspect, a method to recover digital data includes receiving a distorted digital data stream and processing the distorted digital data stream to remove distortions. The processing includes detecting state changes, removing noise and identifying valid pulses. The processing also includes forming an undistorted data stream based on the processing.
