Paley-weiner theorem

WebThe Paley Wiener Theorems in Rn The relationship of the growth of an entire function with the properties of its Fourier transform are embodied in the well known Paley-Wiener theorems. For functions of complex vari-able, we have: Theorem 1 (PW1). A function f :C→C is an entire function of exponential type with its restriction f R ∈L 2(R) iff ...
