If a step function is applied to the input of a system and the output remains below a certain level for all the time, the system is :
A. Not necessarily stable
B. Stable
C. Unstable
D. Always unstable
Answer:A
If a step function is applied to the input of a system and the output remains below a certain level for all the time, the system is :
A. Not necessarily stable B. Stable C. Unstable D. Always unstable
Explanation: If the input is bounded and output is also bounded then the system is always stable and step input is bounded and the output is always under certain li its then the system is stable.
