Abstract
A delta-sigma modulation apparatus performs delta-sigma modulation on a first signal as an input signal and outputs a second signal; learns a parameter for a transmission path distortion model using the second signal and a third signal generated through a transmission path of the second signal; inputs the second signal to the transmission path distortion model and outputs a fourth signal that is an approximated value of a signal which is generated through at least part of the transmission path of the second signal, and performs the delta-sigma modulation on the first signal using the fourth signal and outputs the second signal.
