More useful is the energy carried by this pulse, especially if this is an inrush current. There are many realworld systems that have sawtooth waveforms that maintain a constant peaktopeak voltage/current but have varying DC components. The RMS value changes as a result. How to Derive the RMS Value of a Triangle Waveform

The partials in the sawtooth wave decrease in energy in proportion to the inverse of the harmonic number (1/N). Pulse (or rectangle or square) waveforms have energy over a broad area of the spectrum, but only for a brief period of time. Fourier Series. What exactly is a Fourier series, and how does it relate to phasors?

Since waves are spread out in space and time, energy density is often a more useful concept than energy. By extension, the power of a wave should probably be replaced with the more useful concept of its power density. Since the energy content of a wave fills a volume of space it makes sense to define energy density as energy per volume.

The sawtooth wave (or saw wave) is a kind of nonsinusoidal waveform is so named based on its resemblance to the teeth of a plaintoothed saw with a zero rake angle.. The convention is that a sawtooth wave ramps upward and then sharply drops [citation needed].However, in a reverse (or inverse) sawtooth wave, the wave ramps downward and then sharply rises.

Apr 02, 2009 · The more physical reason (and historical too), as leftyretro already said, is the mechanical AC generator. Because it always provided sinus voltage, and it always will (try making a mechanical swatoothvoltage power generator with reasonable efficiency), we will always have the AC power in form of sinus waves. Sinus also happens to be the most natural periodic function, as it is in many things
