Fourier transformation of some signal shapes

As I’m an electrician I did the Fourier transformations of some wave shapes that are mainly interesting in the Electrical Engineering :-)

The base formulation to build the Fourier transformation of the function f(x) which is periodic to 2π is:
Fourier

And for the backward transformation:
Fourier
