Expert Solution
Step 1

In the given waveform, the signal u(t+2) is advanced by the 2 units. So, it left shifted by 2 units.

The signal u(t-3) is delayed by 3 units. Hence, it is right shifted by 3 units.

Solution:1.f(t) = u (t+2) - u(t-3)   u (t+2) is delayed by 2,left-shifted thus we have:      t+2 = 0       t = -2

 u(t-3) is delayed by 3, thus we have:     t-3 = 0      t = 3

-u(t-3) , thus we have:

Now, for f(t) = u (t+2) - u(t-3)                   = u (t+2) +- u(t-3) As shown below:
