摘要：A method for analyzing a machine having a rotating shaft includes: generatingan electric measurement signal dependent on vibrations emanating from the shaft;sampling the measurement signal at a sampling frequency to generate a digitalmeasurement data signal; performing a decimation of the digital measurement datasignal to achieve a digital signal having a reduced sampling frequency, the decimationincluding controlling the reduced sampling frequency such that the number of samplevalues per revolution of the shaft is kept at a substantially constant value; receiving thedigital signal at an enhancer input; performing a correlation in the enhancer so as toproduce an output signal sequence wherein repetitive signals amplitude components areamplified in relation to stochastic signal components; and performing a condition analysisfunction for analyzing the condition of the machine dependent on the digital signalhaving a reduced sampling frequency.
