Visjnoe,
Ken described Spectre's Fourier Analysis. This analysis
is a basic capability of Spectre and does not require a
SpectreRF license. However, the fourier element
implemented in analogLib is only a subset of the full
functionality and you should probably run Spectre from
the command line(unless you want to modify the CDF
yourself). BTW, Spectre's Fourier analysis is described
in chapter 5 of Ken's book.
Also had a question for Ken
, when using the fourier
integral for analyzing oversampling ADC/DAC is there
any method to window the data? Since for oversampling
ADC/DAC the data is not periodic outside the time
selected for the Fourier analysis, it seems like the
data needs to be windowed to prevent spectral leakage.
Best Regards,
Sheldon
