Question: A filter has a transfer function (a) Find the poles and zeros of H(z 1 ; z 2 ). (b) For what values of z

A filter has a transfer function

-1 1 – 27' H(21, 2) = 1+0.527 +1.5z,


(a) Find the poles and zeros of H(z1; z2).

(b) For what values of ẑ1 and ẑ2 is H(ẑ1, ẑ2) = 0/0?

(c) Ignoring the numerator, i.e., letting

Ĥ (21, 2) -1 1+0.5z7' + 1.52,


is this filter BIBO stable? Show your work.

-1 1 – 27' H(21, 2) = 1+0.527 +1.5z, Ĥ (21, 2) -1 1+0.5z7' + 1.52,
