WebThe gain and phase response of a low-pass filter can be optimized to satisfy one of the following three criteria: 1) A maximum passband flatness, 2) An immediate passband-to-stopband transition, 3) A linear phase response. For that purpose, the transfer function must allow for complex poles and needs to be of the following type: A(s) A0 1 a
