METHOD FOR AMPLITUDE MODULATION AND DEMODULATION OF HIGH-FREQUENCY SIGNALS AND APPARATUS FOR REALISING SAID METHOD |
摘要 |
FIELD: radio engineering, communication.SUBSTANCE: modulation and demodulation apparatus is connected between a source of high-frequency signals and a low-frequency load and is made from cascade-connected matching four-terminal element with at least three two-terminal elements, a three-terminal nonlinear element, a high-frequency load and a low-pass filter; in demodulation mode, the nonlinear element decomposes the spectrum of the amplitude-modulated signals; their amplitude-modulation factor is corrected; the low-pass filter selects the information-bearing low-frequency signal; in modulation mode, resistance values of the two-terminal elements are selected based on the condition of simultaneously providing given ratios of moduli of transfer constants in two states of the nonlinear element.EFFECT: generating and demodulating said types of signals by realising given ratios of moduli of transfer constants in two states of the nonlinear element using one device with signal amplification.2 cl, 5 dwg |
