Explanation: A circuit or a group of circuits connected together as a system is said to be stable, if its output reaches a fixed value in a finite time. 5. Why unstable systems are considered to be impractical?
A. None of the mentioned
B. Output decreases with time
C. Output reaches fixed value
D. Output increases with time
Answer:A
Explanation: A circuit or a group of circuits connected together as a system is said to be stable, if its output reaches a fixed value in a finite time. 5. Why unstable systems are considered to be impractical?
A. None of the mentioned B. Output decreases with time C. Output reaches fixed value D. Output increases with time
Explanation: A circuit is said to be unstable if its output increases with time instead of achieving fixed value. In fact the output keeps on increasing until the system breaks down. Therefore, unstable systems are impractical and need to be made stable. 6. How is the criterion for the system determined?
