L. Knockaert et D. Dezutter, AN EXPONENTIAL TRUNCATION BOUND FOR ANALYTIC FOURIER-SERIES, IEEE transactions on signal processing, 46(3), 1998, pp. 788-790
It is shown that analytic Fourier series admit a uniform exponential t
runcation bound. As a consequence, an explicit expression is obtained
for the number of principal harmonics consistent with a preassigned ad
missible uniform error level.
