  2. What is the equation of a triangle wave?

What is the Fourier transform of triangular signal?

The Fourier Transform of the triangle function is the sinc function squared. Now, you can go through and do that math yourself if you want. It's a complicated set of integration by parts, and then factoring the complex exponential such that it can be rewritten as the sine function, and so on.

What is the equation of a triangle wave?

Triangular Wave

y = abs((x++ % 6) - 3); This gives a triangular wave of period 6, oscillating between 3 and 0.
