# Waveform definition

wāvfôrm
Frequency:
The shape of an audible or electronic signal. On an oscilloscope, analog waveforms show up as smooth curved lines that rise and fall (sine waves), while digital waveforms appear as square-shaped vertical and horizontal lines. See wavelength, sine wave and square wave.
(physics) A graphic representation of a wave, usually plotted with amplitude on one axis and frequency on the other.
noun
The mathematical representation of a wave, especially a graph obtained by plotting a characteristic of the wave against time.
noun
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.
(mathematics) The shape of a wave function represented by a graph showing some dependent variable as function of an independent variable.
noun
(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.
noun

Singular:
