sawtooth wave

 noun

Definitions

1. A sawtooth wave follows a pattern similar to that of a sine wave, a series of alternating high and low voltages. The difference is that a sawtooth wave’s magnitude rises steadily to a maximum, then switches instantaneously to zero. A sawtooth wave is useful for many welding applications.
