tfestimate
显示 更早的评论
Transfer function can be calculated using tfestimate as follows Txy=tfestimate(x,y) According to books this is Txy = Cxy/Cxx. Now if I compute Cxy and Cxx separately Cxy=cpsd(x,y) Cxx=cpsd(x,x) and compute Txy2= Cxy./Cxx the result is different between Txy and Txy2: imaginary parts have minus sign. Why?

Hi arttu,
According to the documentation, the computation is Cyx/Cxx.
Also the following link suggests that it should be Cyx/Cxx
