49.
Choose correct option for a stable system :
- Roots of the characteristic equation of the system are real and negative
- Area within the impulse response is finite
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.
