Summary:The present invention is configured such that a first I signal passed through a first reverse characteristic circuit (1) having frequency characteristics that are reverse to those of a first loop filter circuit (4) is outputted to the first loop filter circuit (4), and a first Q signal passed through a second reverse characteristic circuit (2) having frequency characteristics that are reverse to those of a second loop filter circuit (5) is outputted to the second loop filter circuit (5). La présente invention est configurée de sorte qu'un premier signal I traversant un premier circuit à caractéristique inverse (1), dont les caractéristiques de fréquence sont inverses de celles d'un premier circuit de filtre à boucle (4), est fourni au premier circuit de filtre à boucle (4) ; et un premier signal Q traversant un second circuit à caractéristique inverse (2), dont les caractéristiques de fréquence sont inverses de celles d'un second circuit de filtre à boucle (5), est fourni au second circuit de filtre à boucle (5). 第1のループフィルタ回路(4)と逆特性の周波数特性を有する第1の逆特性回路(1)を通過した第1のI信号が第1のループフィルタ回路(4)に出力され、第2のループフィルタ回路(5)と逆特性の周波数特性を有する第2の逆特性回路(2)を通過した第1のQ信号が第2のループフィルタ回路(5)に出力されるように構成する。
