An Introduction to Wavelets - University of Delaware

coherent theory. 2.1. PRE-1930 Before 1930, the main branch of mathematics leading to wavelets began with Joseph Fourier (1807) with his theories of frequency analysis, now often referred to as Fourier synthesis. He asserted that any 2…-periodic function f(x) is the sum a 0 + X1 k=1 (a kcoskx+ b ksinkx) (1) of its Fourier series. The coe ...
