The algorithms of parametric synthesis of amplifiers and demodulators angle-modulated signals by providing the slope of the amplitude-frequency characteristics of the device with a given slope in the interests of the transformation angle-modulated signals in the amplitude-modulated signals with angular modulation. The result obtained by the mathematical model the matching four-reactive as the optimum relationship between the elements of the transfer matrix for the case of using any number of linear and non-linear elements included on both sides of the quadripole. These relationships are used to form a system of algebraic equations whose solutions yielded mathematical expressions to determine the optimal dependency of reactive two-terminal resistance of the frequency for typical two-port circuits. Implementation of these characteristics carried switched by the quasi-optimal two-terminal in the form of multiple-loop systems, depending on the frequency of resistance which coincide with the optimum in a limited frequency band.
