- (mathematics) The shape of a wave function represented by a graph showing some dependent variable as function of an independent variable.
- (physics, engineering) The shape of a physical wave, such as sound, electric current or electromagnetic radiation, or its representation obtained by plotting a charecteristic of the phenomenon (such as voltage) versus another variable, often time.
waveform - Computer Definition
The geometric shape of a wave. A waveform is used to graphically represent some recurring characteristic of a wave over time. Electromagnetic energy is commonly plotted in two dimensions as a sinusoidal waveform that varies in amplitude (A), or signal strength, on the vertical (V) axis at a periodic rate, or frequency (f), over time (t) on the horizontal (H) axis. See also sine wave.
