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 integer.
Then 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 = exp^jw, and the b and a are constants.
Thx for any help!
