Etymology
The term 'sawtooth' originated from the physical appearance of the teeth of a saw, which are jagged and uneven. The word 'saw' dates back to Old English 'sæw', which is related to the Proto-Germanic '*sawō' and has cognates in other Germanic languages. The suffix 'tooth' comes from Old English 'tōþ', which also traces back to Proto-Germanic '*tōþs'. The sawtooth wave concept emerged in the early 20th century as engineers and musicians began exploring new forms of sound synthesis and wave manipulation. These waves became significant in the development of electronic music and signal processing technologies.
