Convert frequency domain to time domain

Nancy Jewel Mcdonie

Hi all experts, 

I'm doing Frequency Response Analysis, my result is in frequency domain. I know there are some way to convert to time domain (using Altair Compose/HyperGraph math function) but I don't know where to start, what is input....

So can anyone explain for me?

Thanks.

Hi Nancy,

To convert the result from frequency domain to Time domain you need to do IFFT (Inverse Fast Fourier Transformation)by using compose. Please go through the below link for detailed explanation. Initially FFT is explained, later you can find about IFFT.
