Interpolation of a complex transfer function.

Started by Unknown July 25, 2003
Hello all

I have a complex transfer function e.g. like this:

Y=[0.1+0.2i, 0.3+0.77i, 0.11+0.22i]

corresponding to a frequency vector e.g. X = [1, 3, 5]

Now I want to have the frequencies between the points of my
oryginal vector e.g.

X1=[1.2, 2.5, 4.2, 4.8, 4.9]

And I want to find a corresponding vector Y1 of complex values.

The question is whether I can perform an interpolation for
separated values Re(Y1)= interp(Re(Y)) and Im(Y1)=interp(Im(Y))
and the resulting vector Y1 will give me what I want.

I think so, but probably it is wrong, so what is the right

thanks in advance

OK, I got it now,
