Signal Power and Energy

Explains power and energy using examples of signal waveform plots. Note that there is a minor "visual typo" in the plots for power and energy. I drew rectified sine waves by mistake, but they should be sine waves with a vertical offset (ie. the sharp "valleys" should be smooth). This is because sin^2 (x) = 1/2 (1 - cos (2x)). This means that x(t)^2 should be a sinusoid of twice the frequency of the original signal, with a maximum amplitude of 1 and a minimum amplitude of 0.
