摘要

A method for performing the analog to digital conversion of a repeating signal that includes performing the analog conversion of digital data and generating a reference signal, comparing the repeating signal and the reference signal, holding the comparison result at a prescribed time position of the repeating signal, and adjusting the digital data based on the held comparison result. In addition, an apparatus for performing the analog to digital conversion of a repeating signal by implementing the method described above.
