- \( e^{Ts} \)
- \( \frac{1}{Ts+1} \)
- \( e^{-Ts} \)
- \( e^{-Ts+1} \)
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The transfer function for a pure transportation lag (dead time) of \( T \) seconds is \( e^{-Ts} \). This represents a delay in the time domain and is commonly encountered in process control systems.
