  • Abstract
    Resolution of two sinusoidal signals of frequencies f1and f2requires a time record of length at least 1/|f_{1}-f_{2}| . Resolution of two decaying exponentials of complex frequencies s1= σ1+jω1and s2= σ2+jω2, with \\sigma _{2} \\leq \\sigma _{1} , by correlation coefficient is independent of the ratios σ2/σ1, and (ω1- ω2)/σ1for a time record of length greater than 3/|\\sigma _{1}| . This is also the condition for near-orthogonalization of a set of complex exponentials, with small error.
