Abstract
A DSP#B executes, prior to data conversion, interpolation (see FIG. ) in order to interpolate discrete spectra obtained via the FFT processing by a DSP#A . In the interpolation, the DSP#B executes two-point interpolation if the difference between two discrete spectrum data pieces F(j) and F(j+1) is greater than a predetermined threshold &egr; and four-point interpolation if the difference is smaller than &egr;.
