continued-fraction expansion

continued-fraction expansion

[kən′tin·yüd ′frak·shən ik′span·shən] (mathematics) An expansion of a driving-point function about infinity (or zero) in a continued fraction, in which the terms are alternately constants and multiples of the complex frequency (or multiples of the reciprocal of the complex frequency). A representation of a real number by a continued fraction, in a manner similar to the representation of real numbers by a decimal expansion.
