PROBLEM #3 Pole-Zero Placement FD Methods A digital filter is characterized by the following: • It is a lowpass filter and has one pole and one zero. • The pole is at a distance r = 0.9 from the origin of the Z domain • High frequency signals do not pass through this system. Answer the following: 1) Plot the pole-zero pattern of the filter, justify your selections of poles and zeros. 2) Normalize the frequency response so that $H(0) = 1$ and determine $H(z)$. 3) Determine the systems impulse response. 4) Determine $H(\omega)$ and its magnitude and phase response. 5) Find the difference equation representing his filter. 6) Compute the output of the filter if $x(n) = 10 + 5 \sin(0.2\pi n) + 11\cos(0.8\pi n)$ for all n. 7) Use MATLAB for the magnitude plot and decide on the quality of the design.
