PROBLEM TO BE SOLVED: To provide a PWM signal processing device capable of outputting by synthesizing a plurality of PWM signals into one without extending an update period of the plurality of PWM signals.SOLUTION: A unique Duty addition unit 5, when a Duty converter 4 time-sequentially outputs a synthesized PWM signal synthesized into one by successively switching Ach, Bch PWM signals for each carrier period, adds an identification duty pulse for identifying a PWM signal of each channel by masking part of a duty signal of Ach, Bch PWM signals.SELECTED DRAWING: Figure 1 【課題】複数のＰＷＭ信号の更新周期を長期化させることなく、１つに合成して出力できるＰＷＭ信号処理装置を提供する。【解決手段】固有Ｄｕｔｙ付与部５は、Ｄｕｔｙ変換部４が、Ａｃｈ，ＢｃｈのＰＷＭ信号をキャリア周期毎に順次切り替えて、時系列的に１つに合成した合成ＰＷＭ信号を出力する際に、Ａｃｈ，ＢｃｈのＰＷＭ信号のデューティ信号の一部をマスクすることで、各ｃｈのＰＷＭ信号を識別するための識別用デューティパルスを付加する。【選択図】図１
