Square wave — A square wave is a kind of non sinusoidal waveform, most typically encountered in electronics and signal processing. An ideal square wave alternates regularly and instantaneously between two levels. Origins and uses Square waves are universally… … Wikipedia
Square Wave Inverter — A type of inverter that produces square wave output.; consists of a DC source, four switches, and the load. The switches are power semiconductors that can carry a large current and withstand a high voltage rating. The switches are turned on and … Energy terms

Wave equation — Not to be confused with Wave function. The wave equation is an important second order linear partial differential equation for the description of waves – as they occur in physics – such as sound waves, light waves and water waves. It arises in… … Wikipedia
Alternating current — (green curve). The horizontal axis measures time; the vertical, current or voltage. In alternating current (AC, also ac) the movement of electric charge periodically reverses direction. In direct current (DC, also dc), the flow of electric charge … Wikipedia
Cnoidal wave — US Army bombers flying over near periodic swell in shallow water, close to the Panama coast (1933). The sharp crests and very flat troughs are characteristic for cnoidal waves. In fluid dynamics, a cnoidal wave is a nonlinear and exact periodic… … Wikipedia
Periodic current reversal — (PCR) is a current modulation technique that can be used in various electrochemical processes.In the most basic sense PCR simply means that the electrical current applied to the cell is reversed periodically but unlike pure AC the average (nett)… … Wikipedia
Reference current — An ISO term. The minimum recording current amplitude (square wave) which causes on the reference card, under the given test conditions, a readback voltage amplitude equal to 80 % of the maximum amplitude at a density of 8 ftpmm (flux… … International financial encyclopaedia
Root mean square — In mathematics, the root mean square (abbreviated RMS or rms), also known as the quadratic mean, is a statistical measure of the magnitude of a varying quantity. It is especially useful when variates are positive and negative, e.g., sinusoids.It… … Wikipedia
