In this paper we identified a collection of unitary operators which maps Gabor frames in \(L^2(\mathbb{R})\) to Gabor frames in \(l^2(\mathbb{Z})\). This is very important in construction of Gabor frames in \(l^2(\mathbb{Z})\) from Gabor frames in \(L^2(\mathbb{R})\) other than which obtained from Gabor frames in \(L^2(\mathbb{R})\) through sampling.
