Waveform
the shape and form of a signal such as a wave moving in a physical medium or an abstract representation / From Wikipedia, the free encyclopedia
The waveform is the shape of a wave as it travels. There are many different waveforms. They are usually a shape which is repeated over and over (a "periodic waveform"). A common waveform is the sine wave. It is normally not possible to see a waveform without some device.
