Convolution of x(t + 5) with impulse function δ(t

Home » Signals and Systems » Signals and systems electrical engineering miscellaneous » Question

Convolution of x(t + 5) with impulse function δ(t – 7) is equal to

1. x(t – 12)
2. x(t + 12)
3. x(t – 2)
4. x(t + 2)

Correct Option: C

As, g(t)* δ(t – t₀) = g(t₀)
Then, x(t + 5) * δ (t – 7) = x(t – 2)
