  • Abstract
    A new lemma relates the analytic extensions of two time functions u(t) and v(t) to the Laplace transform of their ambiguity function \\psi_{uv} . This lemma is used to derive necessary conditions for u and v from two bounds on the behavior of \\psi_{uv} , at infinity. In particular, if the first bound is fulfilled, then u(z) and v(z) must be integral analytic functions. If both bounds are fulfilled, then u and v are each equal to \\exp {- \\pi t^2 } times a polynomial in t , and the two polynomials can be found from \\psi_{uv} by comparing coefficients.
