Abstract
A sampling circuit for sampling a binary signal and producing an output signal representative of a particular sample of the binary signal. The sampling circuit includes a storage unit to store successive samples of the binary signal which are acquired in a time interval shorter than the time period between two subsequent transitions of the binary signal. A test unit is coupled to the storage unit and is operative to perform the following operations: testing a plurality of successive samples, supplied by the storage unit, for being functionally identical to one another; producing an output signal representative of any of the plurality of successive samples upon detecting the identity; upon detecting the absence of identity among the plurality of samples: testing a further plurality of successive samples, supplied by the storage unit, for being functionally identical to one another; producing an output signal representative of any of the further plurality of successive samples upon detecting identity among the further plurality of samples; and upon detecting the absence of identity among the further plurality of successive samples, producing an output signal representative of a predetermined substitute.
