Abstract:
A circuit for restoring bits transmitted by an asynchronous signal includes a first comparator for comparing the level of the asynchronous signal with a first threshold adjusted as a function of the output of the first comparator during synchronization bursts of the asynchronous signal, and at least a second comparator for comparing the level of the asynchronous signal with a second threshold correlated to the first threshold.
