摘要：
脉冲调制器通过对输入信号的振幅分量进行脉冲调制并放大，来生成脉冲调制信号。低通滤波器对来自于脉冲调制器的脉冲调制信号进行过滤，生成对振幅分量放大后得到的放大振幅信号。误差校正器通过使用输入信号的振幅分量对来自于低通滤波器的放大振幅信号的误差进行校正，生成校正振幅信号。合成器将来自于误差校正器的校正振幅信号和输入信号的相位分量合成起来，生成输出信号。
摘要（英）：

A pulse modulating section generates a pulse modulation signal by pulse-modulating and amplifying the amplitude component of an input signal. A low-pass filter filters the pulse modulation signal from the pulse modulating section, and generates an amplified amplitude signal having the amplitude component amplified. An error correcting section generates a corrected amplitude signal by correcting the error of the amplified amplitude signal from the low-pass filter by using the amplitude component of the input signal. A synthesizing section generates an output signal by synthesizing the corrected amplitude signal from the error correcting section and the phase component of the input signal.
