Response of a system to a sinusoidal input is called _____________ response?
Correct answer: D. Frequency
- A. Impulse
- B. Unit step
- C. None of these
- D. Frequency
Explanation
A sinusoidal input is used to determine a system's frequency response, which describes the steady-state gain and phase at different frequencies. Impulse and unit-step responses correspond to different test inputs.
