Abstract:
A calculating apparatus includes a first state variable calculating unit that calculates first state variables respectively having a memory effect and being of an amplifier that causes signal distortion; an amplifier model unit that based on the calculated first state variables, calculates the signal distortion caused by the amplifier, as a distortion characteristic; and an output unit that outputs the calculated distortion characteristic.
