 F2. Yes. You should assume that both s1(t) and s2(t) are zero outside the duration T. F2. Yes. You should assume that both s1(t) and s2(t) are zero outside the duration T.

 +F3. No. Please refer to Fig. 3.13 in the text. Note that a1(t) is the integral of s1(t). Likewise a2(t) is the integral of s2(t).
