  Matlanb code:

  numerator=[1 4 16 4];

  denomenator=[1 20 12 1 10];

  y=tf(numerator,denomenator)

  [z,p,k]=tf2zpk(numerator,denomenator)

  Result:

  [z,p,k]=tf2zpk(numerator,denomenator)

  z =

  0.0000 + 0.0000i
  -1.8667 + 3.3941i
  -1.8667 - 3.3941i
  -0.2666 + 0.0000i

  
  p =

  -19.3822 + 0.0000i
  -1.0565 + 0.0000i
  0.2193 + 0.6635i
  0.2193 - 0.6635i

  
  k =

  1

  2)

  Matlab Code:

  Matlanb code:

  numerator=[1 0 19.8e4];

  denomenator=[1 648 28.7e4];

  y=tf(numerator,denomenator)

  margin(y)

  Result:

  corner frequency 1000 rad/sec

  bandwidth 800-200 = 600rad/sec
