Abstract
A signal converting apparatus includes a conversion unit, a measurement unit, and a control unit. The conversion unit performs FM batch conversion on an input signal containing a plurality of carrier signals, to generate an FM signal. The measurement unit measures the carrier levels of the plurality of carrier signals contained in the input signal, and the maximum frequency of the input signal. The control unit calculates the frequency deviation amount of the entire input signal, on the basis of the measured carrier levels of the respective carrier signals. Using the calculated frequency deviation amount and the measured maximum frequency, the control unit calculates a center frequency for the FM signal, and controls the conversion unit so that the center frequency of the FM signal to be generated by the FM batch conversion becomes equal to the calculated center frequency.
