Oscilloscope showing a sawtooth waveform. An oscilloscope is a device that produces a waveform as a visual representation of oscillations or changes, usually in an electric current. A sawtooth wave has a shape resembling the teeth of a saw. The amplitude does not vary smoothly, but changes sharply at the peak and trough points.
