Hi ,

 

For finding cross coherence between two signals, we have to find power spectral densities first. But in cces c/c++ library they mentioned following formula:

How this will find the cross - coherence , I no where found a definition for cross-coherence as shown ,

 

Can some one give any reference from where they took the formula, I want to use coherence in  my application

 

Thanks & Regards
