impulse response h = {-4,1,-1,-2,5,6,5,-2,-1,1,-4}
↑
The solution says that M=11, which is odd, and since h is symmetric about about α = (11−1)/2 =
5, this is a Type-1 linear phase FIR filter.
Can someone tell me how it was derived that this filter is symmetric?
impulse response h = {−4, 1,−1,−2, 5, 6,−6,−5, 2, 1,−1, 4}.
↑
The solution says that M=12, and since h is anti-symmetric with respect to α = (12−1)/2 =
5.5, this is a Type-4 linear phase FIR filter.
Can someone tell me how it was derived that this filter is anti-symmetric?
Is symmetry and antisymmetry based on the principal of even and odd signal?
