Abstract: The notion of a frame for Hilbert spaces was introduced by Duffin and Schaeffer [5]. This was done while probing into some questions in non-harmonic Fourier series. This idea seemed to have been unnoticed outside of this area until Daubechies, Grossmann and Meyer brought it into light in 1986. the latter’s showed that Duffin and Schaeffer’s definition was an abstraction of the concept introduced by Gabor in 1946 for doing signal analysis.. In this communication, we will give sufficient conditions for an infinite family in l2(H) to be a frame for H, where l2(H) is the space of square ...
