ABSTRACT:
The invention relates to signal conversion devices to be used for the receiving radio devices. The attained technical result is the detection and conversion of signals in an electrical two-terminal device, a data loss level being minimal. A converting element is supplied with input signals, interaction of the fields of said signals in the converting element material is provided, which interaction is accompanied with the energy interchange resulting in appearance of the efficient electromotive force, and extracted is the converted signal complying with the following ratio:U′(t)=-γ[Rx{ΣUi(t)·Uo(t)+Uo(t)·ΣUi(t)}xolwhere U′(t) is the efficient electromotive force in the converting element, Rxis Hall coefficient of the converting element conductive material (C/m3); l is length of the converting element along the current direction, (m); xois the least one of linear dimensions of the converting element cross-section that is perpendicular to direction of the current flowing therein, (m); γ=τ·εo; εois electric constant, εo≈10−11C/V·m, τ is dimensions factor that represents a degree of interrelationship of the fields in a conductive medium ΣUi(t), where i=l . . . n is the combined voltage of the input convertible signals; Uo(t) is voltage of the input converting signal; at that, the ratio between the physical parameters and geometric parameters of the converting element and the sum of voltages of the input signals is selected with regard to the condition 2γ|Rx|U/xol≧1, where U is sum of voltages of the input signals.
