FIELD: measuring devices. SUBSTANCE: method involves signal receipt, squaring it, band- pass filtering, clipping it within certain limits, halving its frequency, quadrature phase detection, demodulation of phase and quadrature modulation. Quadrature and phase constituents of detected signal are used for quadrature modulation of input signal while sign of one of constituents is inverted. EFFECT: increased field of application. 1 dwg
