  We advance here an algorithm of the synthesis of lossless electric circuits
such that their evolution matrices have the prescribed Jordan canonical forms
subject to natural constraints. Every synthesized circuit consists of a
chain-like sequence of LC-loops coupled by gyrators. All involved capacitances,
inductances and gyrator resistances are either positive or negative with values
determined by explicit formulas. A circuit must have at least one negative
capacitance or inductance for having a nontrivial Jordan block for the relevant
matrix.
