    • Technologies are described for reducing distortion in amplified signals in well logging tools based on spectral analyses of the amplified signals. For example, a system includes a well logging tool. The well logging tool includes an excitation source to direct an excitation signal towards an environment adjacent a wellbore and a receiver to amplify a probe signal received from the environment adjacent the wellbore in response to the excitation signal. The system also includes a feedback module to receive the amplified signal. The feedback module includes a spectrum analyzer module to spectrally analyze the amplified signal to generate spectral information of the amplified signal; and a controller module to determine, from the spectral information, whether the amplified signal includes distortion, and if so, to issue a feedback signal to the excitation source or the receiver to cause at least a reduction of the distortion in the amplified signal.
    • 描述了基于放大信号的光谱分析来降低测井工具中放大信号失真的技术。 例如,系统包括测井工具。 测井工具包括一个激发源,用于将激发信号引向靠近井眼的环境,以及一个接收器,用于响应激励信号放大从邻近井眼的环境接收的探测信号。 该系统还包括用于接收放大信号的反馈模块。 反馈模块包括频谱分析器模块,用于对放大的信号进行频谱分析以产生放大信号的频谱信息; 以及控制器模块,用于从频谱信息中确定放大的信号是否包括失真,如果是,则向激励源或接收机发出反馈信号,以使至少减小放大信号中的失真。
