Explanation / Answer

octave:3> ----------------------------------------------------------------------- num = input('Enter the numerator coefficients =') den = input('Enter the denominator coefficients =) [z,p,k]=tf2pz(num,den) m = abs(p) % To find Dist bet origin and poles disp('Zeros are at'); disp(z); disp('poles are at'); disp(p); disp('gain constant'); disp(k); disp('Radius of poles'); disp(m); dummy= zp2sos(z,p,k); disp(real(dummy)); zplane(num,den); -------------------------------------------------------- >>> ----------------------------------------------------------------------- ^ num = [](0x0) >>> den = input('Enter the denominator coefficients =) ^ Zeros are at poles are at gain constant Radius of poles >>> --------------------------------------------------------
