All ISRO Electronics & Communication (ECE) papers | ISRO Electronics & Communication (ECE) 2009

Topic: Electronics Engineering

Convolution of $x(t+5)$ with impulse function $\delta(t-7)$ is equal to

  • A. $x(t-2)$
  • B. $x(t+12)$
  • C. $x(t-12)$
  • D. $x(t+2)$

Answer: A. $x(t-2)$

Explanation: $x(t)*\delta(t-t_{0})=x(t_{0})$
$x(t+5)*\delta(t-7)=x(t-2)$
