A stable LTI system has a transfer function To make this system causal and stable it needs to be cascaded with another LTI system having transfer function H1(s). The correct choice for H1(s) is
  • a)
    s + 3
  • b)
    s - 2
  • c)
    s - 6
  • d)
    s + 1
Correct answer is option 'B'. Can you explain this answer?

A stable LTI system has a transfer functionTo make this system causal ...
Concept:
An LTI Causal System is BIBO Stable if an only if all the poles are strictly in Left hand side of s-plane.
Calculation:
The impulse function can be written as:

The transfer function has poles at s = -3 and s = 2.
In order to make the system causal and stable, the right-hand side pole must be removed.
Thus, H1 (s) = s - 2 needs to be added in cascade to make the system stable and causal.
