SUMMARY
The expression u(t-2)u(t-a) can be simplified based on the value of 'a'. Specifically, if 'a' is less than or equal to 2, the expression simplifies to u(t-2). Conversely, if 'a' is greater than 2, the expression simplifies to u(t-a). This conclusion is derived from analyzing the behavior of the unit step function, which takes values of either 0 or 1 depending on the value of 't'. Graphical representation further confirms this simplification.
