______________By which of the following the system response can be tested better ?
Correct answer: C. Unit impulse input signal
- A. Ramp input signal
- B. Sinusoidal input signal
- C. Unit impulse input signal
- D. Exponentially decaying signal
Explanation
A unit impulse excites all dynamic modes of a linear system and its response directly gives the system’s impulse response, from which the transfer function can be determined. Ramp and sinusoidal tests are useful for particular performance measures but do not reveal the complete dynamics as directly.
