    • The present invention relates to a method and apparatus for deconvolving a noisy measured signal obtained from a sensor device (100), said noisy measured signal (
      y(t) ) being the sum of the convolution product (
      x(t ) ⊗
      N (
      t ) ) of an input signal (x
      (t) ) of the sensor device, representative of a feature of physical quantity, by a convolution kernel (N(t)) defined by the response function of the sensor device (100) and a noise which interfere with the measure. The method is characterised in that said method comprises an estimate computation step (400) in the course of which a minimal estimate (x
      min (t) ⊗
      N (t) ) of the convolution product of the input signal by the convolution kernel of the sensor device is computed in order that said minimal estimate stays below the noisy measured signal (y(t)) and has at least one point in common with the noisy measured signal (
      y(t) ).
    • 本发明涉及一种用于去卷积从传感器设备(100)获得的嘈杂测量的信号的方法和装置,所述噪声的测量的信号(Y(t))的是所述卷积乘积的总和(X(t)N(t)的 )的输入信号的传感器装置的(X(t))的,代表物理量的特征的,由传感器装置(100的响应函数定义的卷积核(N(t))的)和噪声哪 干扰的措施。 在于,所述方法的特征在于所述方法包括通过所述传感器装置的卷积核在输入信号的卷积的哪一个最小估计((X分钟(吨)N t))的过程中的估计值计算步骤(400) 被计算,以使所述最小估算保持低于嘈杂测量的信号(Y(t))和具有至少一个共同的点与所述测量噪声的信号(Y(t))的。
