Mo. :)
Square wave has odd harmonics with amplitudes of 1/n (n being the 
harmonic). Integrating square gives triangle. Integration is same as 
applying a 6dB/oct slope to the spectrum (starting from DC), aka 
multiplying the spectrum by 1/f. Hence triangle harmonics fall at 1/n^2.

Why yes, I did major in signal processing ;)
