Q2.Two systems H1(Z) and H2(Z) are connected in cascade as shown below. The
overall output y(n) is the same as the input x(n) with a one unit delay. The
transfer function of the second system H2(Z)is
Q6.The differential equation 100 describes a system with an
in
put x (t) and an output y(t). The system, which is initially relaxed, is excited by
a unit step input. The output y(t) can be represented by the waveform
Answer : Option AExplaination / Solution:
100
Applying Laplace transform we get
Roots are s = 1/10, 1/10 which lie on Right side of s plane thus unstable
Q10.A numerical solution of the equation can be obtained using
Newton- Raphson method. If the starting value is x = 2 for the iteration, the
value of x that is to be used in the next step is
Answer : Option CExplaination / Solution:
Substituting x0 = 2 we get
Newton Raphson Method
Substituting all values we have
