METHOD FOR REGULATING A MODELLING FILTER |
摘要 |
The invention relates to a method for regulating a modelling filter (18) which is optimised in a frequency region and is used to model an analog circuit (7) to be tested, wherein single tone excitation signals ui(t) having different excitation frequencies (wi) are successively generated; the generated single tone excitation signals ui(t) are applied to the analog circuit (7) to be tested; the output signals yi(t) emitted by the circuit (7) to be tested in response to the respectively applied single tone excitation signals ui(t) are intermediately stored in a memory (37); the intermediately stored output signals yi(t) are transformed according to a Fourier transformation; the calculated Fourier coefficients are intermediately stored in the memory (37); the complex Wiener transmission functions of a Wiener modelling filter are calculated from the intermediately stored Fourier coefficients. |
