Abstract
In signal processing of the present disclosure, an abnormal correction value as a correction value for correcting a quadrature error that occurs in quadrature modulation is output in malfunction determining processing, and a normal correction value as the correction value is output in calibration processing. The presence or absence of malfunction in the signal processing is determined on the basis of the levels of carrier leak and image leak of the quadrature modulated signal.
