Estimate the transfer function if it consists of
(a) two poles;
(b) a pole and a complex pole pair;
(c) two poles, a zero, and a complex pole pair;
(d) three poles, a zero and a complex pole pair. Hint: It may be useful to solve this program using the MATLAB System Identification toolbox or Seidel's program.
