It is shown, for an arbitrary function f(t), that if there exists a reversible function g(t) such that g(f(t)) is band-limited, then f(t) can be uniquely determined in terms of its samples f(nT/sub s/) sampled with the Nyquist rate of g(f(t)). The application of this result to undersampling is illustrated by examples.>
