Abstract
A data converter that converts an input signal to a signal to be inputted to an amplifier. Specifically, the data converter includes: an amplitude detection section that detects an amplitude level of the input signal; a region determination section that determines 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 that converts 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.
