Question

Derive the trigonometric Fourier series of the following periodic square wave and reduce as far as possible.

x(t) =

6 for -6ms < t < 0 ms

-5 for 0ms < t < 6ms

6 for 6ms < t < 12ms

-5 for 12ms < t < 18ms

etc

Please show all steps with explanations as I really need to understand what's going on. Bonus points if you explain how the coefficients and and harmonics behave in the series but not required
