Multiple choice

Consider two transfer functions:

G1 (s) = $\dfrac{1}{s^2 + as +b}$ and G2 (s) = $\dfrac{1}{s^2 + as +b}$

The 3 dB bandwidths of their frequency responses respectively are

  1. $\sqrt{a^2-4b}, \sqrt{a^2+4b}$
  2. $\sqrt{a^2+4b}, \sqrt{a^2-4b}$
  3. $\sqrt{a^2-4b}, \sqrt{a^2-4b}$
  4. $\sqrt{a^2+4b}, \sqrt{a^2+4b}$
