Abstract
The correction method of the present invention includes a step for respectively inputting a same-signal pair composed of two signals each having the same signal waveform to two input lines of a normalization circuit, and then adjusting the difference between the values of the two offset signals added to those two input lines to make the output of the normalization circuit fixed or coincide with a predetermined value. The correction method further includes a step for respectively inputting to the two input lines of the normalization circuit a fixed-ratio-signal pair composed of two signals in which the ratio between the amplitudes of waveforms is fixed, and then adjusting each of the two offset signals added to those two input lines while the difference between the values of the two offset signals is maintained as is, to make the output of the normalization circuit fixed or coincide with a predetermined value.
