49.
Choose correct option for a stable system :
  1. Roots of the characteristic equation of the system are real and negative
  2. Area within the impulse response is finite
I is true, II is true
I is true, II is false
I is false, II is true
I is false, II is false
Answer: Option
Explanation:

From Statement 1: Roots of the characteristics equation of the system are real and negative i.e. the poles are on the left half plane.

Hence the system is stable.

From Statement 2: Area within the impulse response is finite i.e. it is finite duration signal. It produces a bounded output. Hence system is stable.

So both the statements are true.
