Hi!
I havee aset of transfr functions calcuated with tfestimate and a set of coherence functions calculated with mscoherence. I need the SNR of the signals, and I know that the folowing equation is true:
, where C is the coherence function. Could someone write a simple script to show me how it works in practice?

Simply:
coh % vector calculated by mscoherence
SNRfg = coh ./ (1-coh);
SNR = 10*log10(mean(SNRfg));
