A polynomial $P(s)$ is a Hurwitz Polynomial if all its roots (poles) lie in the left half of the s-plane (LHP).

| Filter Type | Characteristic | Mathematical Property | | :--- | :--- | :--- | | | Maximally flat in the passband. | Magnitude squared is $1 / (1 + \omega^2n)$. | | Chebyshev | Equal ripple in the passband. | Uses Chebyshev polynomials. Sharper cutoff than Butterworth. | | Bessel | Maximally flat group delay. | Best for preserving waveform shape (linear phase). | | Cauer (Elliptic) | Ripple in both passband and stopband. | Uses Elliptic functions. Sharpest cutoff of all. | A polynomial $P(s)$ is a Hurwitz Polynomial if
