Digitizer, waveform generator, conversion method, waveform generation method, and recording medium for recording the program

摘要

An AD converter by sampling at predetermined time intervals, the two analog signals, convert each of the second digital signal and a first digital signal, on the basis of the second digital signal, the digitizer apparatus, the second digital a second signal frequency component calculation unit for calculating a second signal frequency component indicating the components of each frequency of the signal, based on the skew at which the analog signals of the two is sampled by the AD converter, the first for the first digital signal and a skew frequency component calculation unit for calculating a skew frequency component indicative of the phase error for each frequency of the two digital signals, and a second signal frequency component correcting unit on the basis of the skew frequency component to correct the second signal frequency component.
