Fourier transform integral
Example for Fourier transform: We have a signal called x(t) in time we will represent it in terms of the time domain. We also can represent it in another way which is called x(f) we will represent it in terms of the frequency domain.
this is what's called transformation. Fourier Transform is an equivalent representation of the signal.
