I have the transfer function$$ H(z) = \frac{z-.75}{.1 z+.15} $$
how do I find the Poles and Zeros?

Poles are the values of $z$ where the denominator becomes zero; zeros are the values of $z$ where the numerator becomes, well, zero. I presume you know how to find the zeros of a linear function? – 2012-02-03

yes I do. So finding poles and zeros in the z domain is exactly like in the s-domain? – 2012-02-03

Well, that is a function of $z$ in there, no? – 2012-02-03
