What Does Waveform Mean?
A waveform is a graphical representation of a signal in the form of a wave. It can be both sinusoidal as well as square shaped, depending on the type of wave generating input. The waveform depends on the properties that define the size and shape of the wave.
Techopedia Explains Waveform
The input used to create a waveform determines its shape. Square shaped waves represent digital information in the form of a 0 or 1. However, a sinusoidal wave usually shows the exact variation that occurs in the input.
