Homework Statement
IIR filter with poles at .7±j0.2 and zeros at 0.2±j0.7
Calculate H(f) and the Differance Equation when the DC gain |H(f=0)|=4
The Attempt at a Solution
I know to find H(f) I can evaluate H(z) along the unit circle. so H(z) evaluated at z=exp(j2pifT)
However I am unsure how to find H(z) from the givens. I am not sure how to treat the poles and zeroes in this form. (imaginary?)
Any hints or help would be much appreciated it.
Thanks,
