waveform Definition

wave·form (wāv′fôrm′)

noun

a graphic representation showing the shape of a wave that is often periodic and usually plotted with the amplitude of the wave on one axis and time on the other axis, as the sine wave of an electronic signal

waveform Telecom 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.
