Duality Property

Statement:

Duality Theorem states that if x(t) has a fourier transform X(w), then if we form a new function of time that has the functional form of the transform X(t), it will have a fourier transform x(w) that has the functional form of the original time function (function of frequency).

Mathematically, it can be written as
