Zeros and poles
Hello.
I have a home exam, and I have some trouble with plotting the zeros and poles of a filter.
H(z) = 1/K ((1+z^1+z^2+...+z^(K-1)) / z^(K-1))
I have found that the pole is at z=0.
I have also worked out that there will be zeros at z^K = 1
Where z = e^(j*2*pi*k/K)
Where will these zeros appear on the zero-pole-plot?
I would really appreciate your help on this.
