By which of the following the system response can be tested better?
Right Answer is:
Unit impulse input signal
The system response can be tested better with the Unit impulse input signal.
A unit step or unit impulse is a baseline input or test input. A unit impulse response reveals a plant time constant, time delay, and gain in a transparent way. These parameters can be determined by the graphical display. For this reason, the step response test is widely used by the process engineer as the first step to access the plant information.
