A Sawtooth Wave

A Sawtooth Wave. Fairly general, even discontinuous, periodic functions can be written as an infinite series in sines and cosines: a 0 + a 1 sin(x) + b 1 cos(x) + a 2 sin(2x) + b 2 cos(2x) + a 3 sin(3x) + b 3 cos(3x) + ..... Such expansions are called Fourier series.If the y-axis lies halfway bewteen two of the discontinuities in the sawtooth, a formula for the sawtooth wave is something like

Sawtooth Function (Wave) - Calculus How To

The sawtooth function, named after it's saw-like appearance, is a relatively simple discontinuous function, defined as f (t) = t for the initial period (from -π to π in the above image).. This periodic function then repeats (as shown by the first and last lines on the above image). The additional periods are defined by a periodic extension of f (t): f (t + kT) = f (t).

A triangle wave has a symmetrical rise and fall of the waveform, but a sawtooth (also called a ramp oscillator) rises very sharply (ideally instantaneously) and then falls gradually. Triangle waves contain an infinite number of odd harmonics, which are often used in synthesizing musical sounds. They sound like horns and trombones.
