Design of symmetric lossless LC filter with analysis of critical element changes

Abstract –

The paper presents the design of analog filter basedon a new class of all-pole approximation. The approximatingfunction is derived using Lege ndre orthogonal polynomial withthe appropriate weights and the usage of two Legendremultiplication factors (at the origin and at the passband edgefrequency). The design procedu re is illustrated on LC ladderfilter (inductors L, capacitors C) and analysis of the criticalelement changes of the 11th-order filter. The whole process of thedesign and optimization is automated using softwareMathematica.
