Physics · Control Systems
The transfer function of a continuous-time linear time-invariant system is given by H(s) = 1s3. Express its impulse response h(t) in terms of the unit step signal u(t), where ⊗ denotes convolution.
- 1u(t) ⊗ u(t)
- 2u(t) ⊗ u(t) ⊗ u(t) ⊗ u(t)
- 3u(t) × u(t) × u(t)
- 4u(t) ⊗ u(t) ⊗ u(t)✓
Correct answer
u(t) ⊗ u(t) ⊗ u(t)
