This paper considers the possibility of achieving improvements in the reliability of synchronizing an asynchronous signal, by exploiting redundancy and masking. Redundancy and masking techniques have been applied successfully to mask both permanent and transient hardware faults. However, it is shown in this paper that redundancy and masking techniques are ineffective against synchronization failures which arise because of metastable behavior of synchronizing elements.
