摘要： A signal processor for removing at least one unintended signal component from an input signal (ua) is proposed. The signal processor includes a filter device (130) and a processing device (150). The filter device (130) filters the input signal (uâ) and generates a filtered signal (uf), which includes the unintended signal component to be removed. The processing device (150) generates an output signal (um), which indicates a deviation of the input signal (ua) from the filtered input signal (uf). By detecting the unintended signal component first an removing this component from the input signal (uâ), the input signal will not be manipulated directly but the unintended signal component in the input signal (uâ) will be compensated. This allows to remove the unintended component from the input signal (uâ) with less distortions of the interesting components in the input signal (uâ).
