Find the range of times over which y (t) is not zero
Let y (t) = x (t) ? h (t) and let x (t) = rect (t + 4) ? rect (t ? 1) and let h (t) = tri (t ? 2) + tri (t ? 6)
All non-zero values of x are in the time range and all non-zero values of h are in the time range . If h is time inverted in the convolution process its inverse is non-zero in the time range . If the time inverse of h is then shifted to the left by more than 3.5, the two non-zero ranges do not intersect and the convolution value is zero. If the time inverse of h is shifted to the right by more than 8.5 the same result occurs. So the range of times is .
