Question

Given \( h(t) = \delta(t-1) + \delta(t-3) \), find step response at \( t = 2 \).

• A. 0
• B. 1
• C. 2
• D. 3

Hint:

Impulse response integrates to step response.

Answer 1

The Correct Option is B

Step response \( s(t) = \int_{-\infty}^{t} h(\tau) d\tau \) So, \[ s(t) = u(t-1) + u(t-3) \] \[ s(2) = 1 + 0 = 1 \]
