Band-limited expansion
The Endeavour 2024-10-28
Summary:
The band-limited expansion of the function f(x) is given by where sinc(x) = sin(πx)/πx. This is also called the sinc expansion, or the Whittaker cardinal after its discoverer E. T. Whittaker [1]. This is called the band-limited expansion of f because each term in the infinite sum is band-limited, i.e. only has Fourier spectrum within […]
