Fourier series for a sawtooth wave with period 2L (= 4)

Fourier series for a sawtooth wave with period 2L

where to insert sawtooth code in this fourier series?

T = input ("Enter the period:");
n = input ( "Enter number of terms of fourier series to calculate:");
t = 0:2*T:10;

y=0;
 for i = 1:n
  y =  (y+(-(2/pi))*(sin(i*pi*t/2))/i);
end
plot(t,y)

Hi,

You could have a look at the following page to understand derving the fourier series from a Sawtooth waveform:

Fourier Series - Sawtooth Waveform

The equation can be implemented in MATLAB. The following MATLAB documentation links to Natural Logarithm, Exponential functions would be helpful to implement the equation.

Hope it helps!
