Abstract
A frequency modulation circuit includes a calibration-operating part which calculates primary calibration values of modulation index at central frequencies of respective ones of n pieces of TF bands which constitute the entire TF range. Interpolation-calculation part performs an interpolation-calculation with respect to the n pieces of primary calibration values and calculates calibration values at intermediate frequencies of central frequencies of neighboring ones of TF bands while calculating calibration values at frequencies at both ends of entire TF range to obtain (n+) pieces of interpolated calibration values as secondary calibration values. Calibration value supply part supplies one calibration value corresponding to the TF bands set in the TF band setting part from among the primary calibration values or secondary calibration values to a modulation part performing frequency modulation together with calculation based on the supplied calibration value.
