FRF of sine sweep data

FRF of sine sweep data

FRF of sine sweep data

(OP)
How do I calculate FRF of sine sweep input?

RE: FRF of sine sweep data

I take it you have one input, the swept sine wave, and one output?  

FRFs can be calculated in several ways.  A common method is to take divide the cross spectral density by the input autospectral density (CSD/ASD).

RE: FRF of sine sweep data

However there is a horrible gotcha with sine sweep, if your analysis frames are shorter than the sweep length.

So, please describe your test conditions and the analysis you need.

Cheers
