x(t) is nonzero only for $T_x$<t<${T}'x$ , and similarly, y(t) is nonzero only for $T_y$<t<${T}'y$. Let

z(t) be convolution of x(t) and y(t). Which one of the following statements is TRUE?

- z(t) can be nonzero over an unbounded interval.
- z(t) is nonzero for t<($T_x$+$T_y$)
- z(t) is zero outside of $T_x$+$T_y$<t<${T}'_x+{T}'_y$
- z(t) is nonzero for t>${T}'_x+{T}'_y$
