hi,
I'm studying for a test, and found this question in one of the previous exams but there is no solution and I was not able to solve it myself.
It would be very helpful if anybody could help =]
h(t) is an analog IIR filter, with the poles λ_1 = -1, λ_2 = -1+i, λ_3 = -1-i and no zeros. let h[n] be a digital IIR filter with poles which defined by e^λ_i and no zeros. is h[n] a high pass filter?

I thought about using some transformation or something like that
but i got stuck, and was unable to prove/disprove.
Thanks.
