Signals and Systems - Power and Energy level signals calculation

AI Thread Summary
The discussion focuses on calculating power and energy levels of signals in the context of signals and systems. Participants express uncertainty about how to approach the calculation of energy levels for signals that extend to infinity. The integral of f²(t) from negative to positive infinity is highlighted as a key consideration for energy calculation. For average power, the suggested method is to integrate f² over one period and then divide by that period. The conversation emphasizes the importance of understanding these calculations in signal analysis.

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.
