    • 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 (u â ) and generates a filtered signal (u f ), which includes the unintended signal component to be removed. The processing device (150) generates an output signal (u m ), which indicates a deviation of the input signal (ua) from the filtered input signal (u f ). By detecting the unintended signal component first an removing this component from the input signal (u â ), the input signal will not be manipulated directly but the unintended signal component in the input signal (u â ) will be compensated. This allows to remove the unintended component from the input signal (u â ) with less distortions of the interesting components in the input signal (u â ).
    • 提出了一种用于从输入信号(ua)中去除至少一个非预期信号分量的信号处理器。 信号处理器包括滤波器装置(130)和处理装置(150)。 滤波器装置(130)对输入信号(u& acirc; )进行滤波并产生滤波后的信号(uf),其包括将被移除的非期望的信号分量。 处理装置(150)产生指示输入信号(ua)与经滤波的输入信号(uf)的偏差的输出信号(umin)。 通过首先检测非预期信号分量从输入信号中去除该分量,输入信号将不会被直接操纵,而是输入信号中的非预期信号分量(u acirc â )将得到补偿。 这允许从输入信号(u â )中去除非预期分量,而输入信号中的有趣分量的变形较小(u â )。
