    2. Relevant equations

    3. The attempt at a solution

    I wasn't really sure where to start with. Can energy level be calculated at any of these, since the signal stretches to infinity?

    I'm very thankful for any hint or solution.

    Well, what does ∫f2(t)dt with lower limit = -∞ and upper limit = +∞ look like?

    As for average power, easiest is to just integrate f2 over 1 period and divide by the period.
