<p>First and second amplifiers 21, 22 amplify a voltage value of a first signal A and generate first and second amplified signals LA, HA. Third and fourth amplifiers 23, 24 amplify the voltage value of a second signal B and generate third and fourth amplified signals LB, HB. A corrector 41b corrects one of the first amplified signal LA and the second amplified signal HA based on a first correction function illustrating a relationship between the voltage value of the first amplified signal LA and the voltage value of the second amplified signal HA and generates one of a first corrected signal CA and a second corrected signal CA', and corrects one of the third amplified signal LB and the fourth amplified signal HB based on a second correction function illustrating a relationship between the voltage value of the third amplified signal LB and the voltage value of the fourth amplified signal HB and generates one of a third corrected signal CB and a fourth corrected signal CB'.</p> |
