I am trying to find the formula to generate the waveform below. By using harmonics on standard sine waves and then combining the outcomes, I have managed to generate, triangle, sawtooth and square waveforms but I am having great difficulty generating this one. Is there another basic waveform I have missed that is required to generate this wave ?
Sine wave harmonics, sawtooth waveform modified

0You can make it by adding a [triangle wave](http://en.wikipedia.org/wiki/Triangle_wave) and a [square wave](http://en.wikipedia.org/wiki/Square_wave). – 2011-04-18

0find the fourier coefficients by integrating (if it is simple enough; i cant see the picture) $\int_Tf(x)\cos(2\pi nx/T),\int_Tf(x)\sin(2\pi nx/T)$ – 2011-04-18
