1. A method for correcting data which are generated by two asynchronous sources, the data from one source, which are present with a first clock, being conducted via a register which is clocked with a second clock assigned to the other source, wherein the output data of the register and output data that are delayed by at least one clock period of the second clock are compared with one another and wherein, in the event of deviations which are greater than a predetermined value, temporally adjacent data, as corrected data, replace the output data of the register.
