Use the fact that if g(jω) is the transfer-function corresponding to a linear system with real coefficients then g(jω) ∗ = g(−jω) and |g(jω)| 2 = g(jω) ∗g(jω) = g(−jω)g(jω) to show that an asymptotically stable second-order butterworth filter (n = 2) has a transfer-function of the form g(jω) = 1 (s − s1)(s − s2) in which s1 and s2 are on the unit circle
