Abstract
We calculate for several g ¿ L2(R) and for integer values of 1/ab the frame bounds and, when possible, the minimum energy dual functions °¿ for the set of time-frequency translates of g corresponding to the lattice parameters a, b. For this we use a recently derived expression for frame bounds and biorthogonal functions in terms of translates of g corresponding to the complementary lattice with parameters 1/b, 1/a.
