Abstract
A first interpolation sectionand a second interpolation sectionperform sampling on input data Idand Qdhaving a sampling frequency fover so that resulting data will have a sampling frequency fsamp, which is equal to an operating clock frequency of a digital-to-analog converter, which is an output destination. In the above manner, the data is interpolated. At this time, the first interpolation sectionand the second interpolation sectionperform interpolation using a frequency ratio between the sampling frequency fover and the sampling frequency fsamp. Then, output data Idand Qdhaving the sampling frequency fsamp is outputted to a quadrature modulation section
