Abstract

СПОСОБ ПЕРЕДАЧИ И ПРИЕМА ИНФОРМАЦИИ, заключающийс  з том, что на передающей стороне модулируют сигнал несущей частоты, а на приемной стороне демодулнруют сигнал несущей частоты, отличающийс  тем,, что, с целью повышени  помехоустойчивости передачи при симметричных помехах, на передающей стороне сигнал несущей частоты модулируют сигналом поднесущей частоты, противофазно измен ют амплитуды верхней и нижней боковых частот модулированного сигнала по закону информации, а на приемной стороне демодул цию сигнала несущей частоты осуществл ют путем определени  разности амплитуд верхней и нижней боковых частот модулированного сигнала. .THE METHOD OF TRANSMITTING AND RECEIVING INFORMATION, which means that the carrier side modulates the carrier signal and the carrier side demodulates the receive side, characterized in that, in order to improve the noise immunity of transmission with symmetrical interference, the carrier frequency signal is modulated on the transmitting side subcarrier frequency signal, the amplitudes of the upper and lower side frequencies of the modulated signal are antiphasically modulated according to the law of information, and on the receiving side the demodulation of the carrier signal This is done by determining the amplitude difference between the upper and lower side frequencies of the modulated signal. .
