Question - 7
(b) K(s) =


is stable as the roots of the characteristic equation have negative real part. The
oots with positive real part lead to an infinite output response indicating unstable system.

Question – 4
Transfer Function G (s) =



Magnitude of G(s)
G (s) =


=


G (jω) =



Hence Gain = 1/4
| G (jω)|=



And The phase angle
Φ = < G (jω) = Tan-1


- Tan-1

- Tan-1

- Tan-1 ω
At ω = 0.1 rad/s, i.e. substituting values in above equation
| G (jω)|= 1.6642, < G(jω) = -9.0501
At ω = 400 rad/s
| G (jω)|= 1.5625 x 10-6 , < G(jω) = - 1. 7971 x102
