发明名称 Method for detecting non-linear behavior in a digital data transmission path to be examined
摘要 PCT No. PCT/DE93/00109 Sec. 371 Date Aug. 26, 1994 Sec. 102(e) Date Aug. 26, 1994 PCT Filed Feb. 3, 1993 PCT Pub. No. WO93/17348 PCT Pub. Date Sep. 2, 1993The transmission path (4) is fed with a test signal (M'), which is generated from a sequence (m) of spectral components (S1 . . . S10), which are distributed equidistantly in the frequency domain, as the result of combining with an additional function (ZSF). The additional function (ZSF) is selected so as to allow the test signal (M') to contain, besides the spectral components (S1 . . . S10)of the sequence (m), additional spectral components (ZS1 . . . ZS21). An output signal (M'') received on the output side of the path is evaluated at evaluation frequencies (AW1 . . . AW10), in the case of which the test signal (M') is free per se of spectral components and, in the case of which, the test signal (M'), after a self-convolution, exhibits additional spectral components (SA1 . . . SA10). The additional spectral components (SA1 . . . SA10) occurring at the evaluation frequencies (AW 1 . . . AW 10) allow a non-linearity of the transmission path (4) to be immediately detected.
