1 b is then finite The ordinary Fourier transform of x(t) is therefore guaranteed to exist In this case the Fourier representation of the signal x(t) = e−btu(t) is given
fouriertransform notes
The functions g(t) and G(f) are said to constitute a Fourier transform pair, and one is called the mate of the other * For a signal g(t) to be Fourier transformable, it
