Digitizer module for converting a pair of analog signals in a pair of digital signals with the same sampling time, which comprises:an a / d - transducer to the scanning of the pair of analog signals in a predetermined time interval and to their conversion into a first and second digital signal;a calculating unit for a second signal frequency component for calculating a second signal frequency component, which is a component of each frequency of the second digital signal, on the basis of the second digital signal;a calculating unit for an offset frequency component for calculating a displacement frequency component, the a phase error of each frequency of the second digital signal corresponding to the first digital signal, on the basis of a displacement of a period of time, with which the pair of analog signals due to the a / d - transducer is scanned; anda correction unit for the second signal frequency component for correcting the second signal frequency component on the basis of the offset frequency component.
