Abstract
N (N≥2) D/A converters convert respective input data at a sampling frequency FS. A digital signal processing unit generates N items of sub-band waveform data. Each of N items of sub-band waveform data is generated by frequency-shifting corresponding one of N sub-band components included in digital waveform data that represents the analog output signal, such that each sub-band waveform data has its maximum frequency below FS/2. A local signal generating circuit generates N local signals having different frequencies.
