Partials for a normal triangle wave: 1/(1^2) * sin(x) + 0 + -1/(3^2) * sin(3x) + 0 + 1/(5^2) * sin(5x) + 0 + -1/(7^2) * sin(7x) et cetera.. --> infinity Partials for a phase corrected triangle wave: 1/(1^2) * sin(x) + 0 + 1/(3^2) * sin(3x) + 0 + 1/(5^2) * sin(5x) + 0 + 1/(7^2) * sin(7x) + et cetera.. --> infinity (http://funsseelen.eu/C/fourier_series/triangle.c / http://funsseelen.eu/C/fourier_series/triangle2.c C code to calculate samples that create both wave forms) Regards, Funs
