Let T denote an operator on a Hilbert space β’ β’ , and let f i β i=1 be a frame for the orthogonal complement of the kernel N T . We construct a sequence of operators n of the form n β’ = n i=1 β’ g n i f i which converges to the psuedoinverse T β of T in the strong operator topology as n β β. The oper
