Waveform

Technology / Home Audio / Waveform: The waveform of a signal is a depiction of its instantaneous voltages versus time. In audio, for example, we are always dealing with periodic waveforms that make up what we hear. These periodic waveforms can be plotted on a graph and will show up as some type of squiggly line. The graph chart rom left to right represents time and from top to bottom is the amplitude of the sound or voltage at those points in time. The familiar sine wave is an example of this.
