Abstract: |
|||
| A digital frequency converter is provided that maintains a high power efficiency in an EER scheme despite the inclusion of digital signal processing. An inputted modulated signal is converted into phase information and amplitude information of a polar coordinate type. The amplitude information is outputted as amplitude information of the digital frequency converter. Meanwhile, phase change of a frequency f 2, which is outputted from an accumulator, corresponding to lower | |||
