Webtions such as the z-Transform, the Fourier transform, or the Laplace transform. Often it is quite hard to quickly ﬁnd the appropriate transform in a book or the Internet, much less to have a good overview of transformation pairs and corresponding properties. In this document I present a handy collection of the most common transform pairs and WebFourier Transform Pairs (contd). Because the Fourier transform and the inverse Fourier transform differ only in the sign of the exponential’s argument, the following recipro-cal relation holds between f(t) and F(s): f(t) −→F F(s) is equivalent to F(t)−→F f(−s). This relationship is often written more econom-ically as follows: f(t ...
