Chapter 4: Programming with MATLAB - FET

Fourier Series
x(t) = a 0 + Σ n=1 ( a n cos nω 0 t + b n sin nω 0 t )
Evaluate the following function:
x(t) = 0.5 + 2/π ( cost – 1/3 cos 3t + 1/5 cos5t –
1/7 cos7t + … ) for -10 < t < 10.
By using different colors plot the following:
1- The first two terms.
2- On the same figure plot the first three terms.
3- On the same figure plot the first four terms.
4- On the same figure plot the first five terms.
5- By using the general form of the function, and by using the for
or while or … loop. Set n as input variable, On the same figure
plot the first one-hundred terms.
