10-3. A stable Butterworth filter H(s) for N = 2 is given by H(s) = 100 s² + 35.3553 s + 625 (a) Compute and plot the poles of H(s) in the s-plane. Write the poles in both rectangular and polar form. (b) Compute the Half-Power bandwidth få in Hz. (c) Plot |H(f)| and label important frequencies and magnitudes. ANS: (a) Polar: s = 25 e‡j 3π/4, Rect: -17.678 ±j 17.768 (b) WB = 625: = 25 ⇒ fB 25/2π = 3.98 =
