WebWe have already seen that rect(t=T) ,T sinc(Tf) by brute force integration. The scaling theorem provides a shortcut proof given the simpler result rect(t) ,sinc(f). This is a good point to illustrate a property of transform pairs. Consider this Fourier transform pair for a small T and large T, say T = 1 and T = 5.
