The Shannon wavelet has an interesting plot: Given the complexity of the plot, the function definition is surprisingly simple: The Fourier transform is even simpler: it’s the indicator function of [-2π, -π] ∪ [π, 2π], i.e. the function that is 1 on the intervals [-2π, -π] and [π, 2π] but zero everywhere else. The Shannon […]
