Question

Let the signal ݂$f(t) = 0$ outside the interval $[T_{1},T_{2}]$, where ܶ$T_{1}$ and ܶ$T_{2}$ are finite. Furthermore, $\mid f(t) \mid < \infty$. The region of convergence (RoC) of the signal’s bilateral Laplace transform $F(s)$ is

• A. a parallel strip containing the ݆$j\Omega$ axis
• B. a parallel strip not containing the ݆$j\Omega$ axis
• C. the entire $s$- plane
• D. a half plane containing the ݆$j\Omega$ axis
