waveform

The mathematical representation of a wave, especially a graph obtained by plotting a characteristic of the wave against time.

The shape of a wave function represented by a graph showing some dependent variable as function of an independent variable.

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.

the shape of a wave illustrated graphically by plotting the values of the period quantity against time
