Power of signal can be calculated as. P = ∫ 0 T u 2 ( t) d t. . My idea is to express u (t) and solve equation. ∫ 0 T u 2 ( t) d t = 1.5. (after solving integral I will get some function of k, f (k), and solve f (k)=1.5). But u (t) is piecewise defined, it is k+2 ...

WebMay 7, 2024 · Add a comment. 1. Power of a sine wave is not dependent on the period (or frequency for that matter). It is only computed from the root mean square (RMS) value of your sine wave and the phase difference between current and voltage. RMS value is given by dividing the peak value of a signal (voltage for example) by the square root of 2. In electric circuits, the signals may represent current or voltage. Consider a voltage v(t) applied across a resistance R and i(t) is the current flowing through it as shown in the figure. … See more A signal is said to be an energy signal if and only if its total energy E is finite, i.e., 0 < 𝐸 < ∞.
