ABSTRACT:
In a quality monitoring method it is proposed that in continuous operation a test signal be generated, digitized, logarithmized, followed by the calculation of a frequency distribution of the test signal amplitude. The frequency distribution can then be integrated in individual areas, the result for each area forming a feature of the test signal. The features of a test signal are combined into vectors, which can be used for a better evaluation of the quality of the production plant.
