continued-fraction expansion [kǝn`tin·yüd `frak·shǝn ik`span·shǝn] MATHEMATICS 1. 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). 2. A representation of a real number by a continued fraction, in a manner similar to the representation of real numbers by a decimal expansion. |
