engineering recuitment HPCL Junior Executive 2025 Mock Test Control Systems Time Response Analysis Time Response of the First and Second Order System
If the response of LTI continuous time system to unit step input is \(\left( {\frac{1}{2} - \frac{1}{2}{e^{ - 2t}}} \right)\), then impulse response of the system is
1
\(\left( {\frac{1}{2} - \frac{1}{2}{e^{ - 2t}}} \right)\)
2
\(\left( {{e^{ - 2t}}} \right)\)
3
\(\left( {1 - {e^{ - 2t}}} \right)\)
4
Constant
