Abstract:
Disclosed is a harmonic compensation device capable of effectively reducing the harmonic distortion of an analog output signal. The harmonic compensation device includes a harmonic compensator, a mixer, a digital-to-analog converter, and an analog output circuit. The harmonic compensator is configured to generate a digital compensation signal according to a digital input signal, in which the digital compensation signal includes the harmonic components of the digital input signal. The mixer is configured to generate a digital output signal according to the digital input signal and the digital compensation signal. The digital-to-analog converter is configured to generate an analog input signal according to the digital output signal. The analog output circuit is configured to generate an analog output signal according to the analog input signal.
