A calculating apparatus (101) includes a first state variable calculating unit (121, 122, 123, 124, 124) that calculates first state variables respectively having a memory effect and being of an amplifier (240) that causes signal distortion; an amplifier model unit (130) that based on the calculated first state variables, calculates the signal distortion caused by the amplifier (240), as a distortion characteristic; and an output unit (130) that outputs the calculated distortion characteristic.
