Hi Guys,
I'm simulationg a circuit in Pspice and parallel trying to calculate it in Mathcad.
I have tested the FFT in Pspice and the cfft in Mathcad and there is a difference in the amplitude, so the scaling.
The one in Mathcad is scaling with 1/n I think. Can you tell me what expression does Pspice use for the FFT?
or explain why i Have such different results? normally even if the sampling step is different I schould have the same Amplitude in the same Frequency..no?
Thank you very much
