I am confused about a lot of Fourier transformations:

- A Fourier transform with variable [tex]f[/tex]
- A Fourier transform with variable [tex]e^{jw}[/tex]
- Fourier series

What is the difference between these different Fouriers?

Another thing, when does the convolution in the time domain become a multiplication in the frequency domain in the above Fouriers? I read that there are some conditions for that.

Thanks in advance
