Ok, i clearly don't understand how to use the formating;), but i can attach a photo of the equation if you doent see what it says?

Thx for answer, and I see that solves it for what I first asked for. But then i get squareroots and I still can't get it in the form I want: H([e]^{}[/jw]) = [[b]_{}[/0]+[b]_{}[/1][e]^{}[/-jw]+...+[b]_{}[/m][e]^{}[/-jmw]]\frac{}{}[/1-[a]_{}[/1][e]^{}[/-jw]+...+[a]_{}[/n]*[e]^{}[/-jnw]]...

Hi! New go on my problem with LTI-system which really is a math-problem: My problem i can't solve: Compute the System Function H(z) from the Frequency H(e^jw)=2*exp^(-j*3/2*w)*[cos(w/2)]^2 In other words i need to reshape the equation where i only have exp^(-j*k*w), where k is an...

I get to the point where: H(e^[jw]) = e^[-j(w/2)] * (1 + 2e^[-jw] + e^[-j2w]) but then I am stuck..

Hi! I have a problem i can't solve: Compute the System Function H(z) from the Frequency H(e^jw)=2e^(-j 3/2 w) 〖[cos(w/2)]〗^2 The answer should be in the form: H(z)= (b_0+b_1 z^(-1)+b_2 z^(-2)+⋯)/(1-a_1 z^(-1)-a_2 z^(-2)-…) where z = e^jw, and the b and a are constants. Thx...
