FIELD: radio engineering, communication.
SUBSTANCE: method for amplitude, phase and frequency modulation of a high-frequency signal is based on interaction of a high-frequency signal and a low-frequency signal with a multifunctional apparatus made from a three-terminal nonlinear element, a complex two-terminal element, a matching four-terminal element and a load, wherein in frequency modulation mode, energy of the dc voltage source is converted to energy of a high-frequency signal; amplitude and phase of the high-frequency signal are changed under the action of a low-frequency control signal, wherein frequency characteristics of parameters of the four-terminal element are selected in accordance with given mathematical expressions. The multifunctional apparatus has a dc voltage source, a three-terminal nonlinear element, a reactive four-terminal element, a complex two-terminal element, a low-frequency control signal source and a load.
EFFECT: providing amplitude, phase and frequency modulation using one device according to the law of variation of the amplitude of a low-frequency control signal.
