摘要 |
The present invention is directed to a data converter for converting an input signal to a signal to be inputted to an amplifier. The data converter includes: an amplitude detection section for detecting an amplitude level of the input signal; a region determination section for determining whether or not an input power to the amplifier is in a non-linear region of the amplifier based on the amplitude level of the input signal detected by the amplitude detection section; and a signal processing section for converting the input signal to a signal having a lower resolution than that of the input signal if the region determination section determines that the input power to the amplifier is in the non-linear region of the amplifier. |
