Homework Statement
A filter with the following impulse response
h(k)=(-.75 .5 0 -.5 .75)
find H(z)
Is its a linear phase system?
Is it a high pass filter?
Homework Equations
h=[c0, c1, c2, c1, c0] <--- I think this is valid for this problem anyway
The Attempt at a Solution
So if i understand this properly for my H(z) I get.
[itex] H(z)=-0.75+0.52z^{-1}-0.5z^{-3}+0.75z^{-4}[/itex]
Then to find out weather or not this is a linear phase system I find my H(f) frequency response?
I get
[itex]H(f)=-0.75+0.5e^{-j\theta}-0.5e^{-3j\theta}+0.75e^{-4j\theta}[/itex]
First off, Am I on the right track here?
Thanks for the help,
