Consider the following statements regarding the advantages of closed loop negative feedback control systems over open loop systems:
1. The overall reliability of the closed loop systems is more than that of open loop system.
2. The transient response in the closed loop system decays more quickly than in open loop system.
3. In an open loop system, closing of the loop increases the overall gain of the system.
4. In the closed loop system, the effect of variation of component parameters on its performance is reduced.
Of these statements are correct.
1. 1 and 3
2. 1 and 2
3. 2 and 4
4. 3 and 4
