Complex Analytic Signals
Complex Analytic SignalsIt is very convenient to describe a given real signal (such as an optical field) via an associated complex quantity. This way, many nuisances due to trigonometry are avoided. The key is to realize that a real signal, Ur(t), has a Fourier transform that is Hermitian,
