Question

For iv, v and vi.

In on p.49 of [1] a windowed decaying exponential signal is given by:
f,1)=e* {u(t-0.25)-u(t–1.5)}
and plotted in MATLAB as in Fig. 1.
which can also be mathematically written as:
e for 0.25s < t<1.5s
-21
for ts0.25s and t20.25s.
Consider the decaying exponential signal.
f()=e"; -0SIS0, a>0.
