Abstract
A lot of work has been done in the field of finding approximation of signals of Fourier–Laguerre series. Many researchers studied approximation of signals of Fourier–Laguerre series using Ces\(\grave{\text {a}}\)ro means, harmonic means, Euler summability means, (C, 2)(E, q) means. Also some researchers worked on approximation of signals of Fourier–Laguerre series using product summability, but upto now no work is done on approximation of signals of Fourier–Laguerre series using double summability. In present problem, we will prove a theorem on approximation of signals of Fourier Laguerre series by \(E_l^1E_l^1\) product Summability.
