Abstract
A data acquisition circuit and method according to embodiments of the invention insert overflow states into a data storage unit among samples of input data and associated time tags that are of interest. The overflow states allow multiple overflows of the time tags without intervening samples of input data being stored, thus allowing the infrequent capture of samples of the input data while maintaining accurate timing data. Also, the overflow states obviate the need to store an overflow status flag with each stored sample of input data and time tag in the data storage unit.
