DEMODULATOR Russian patent published in 2020 - IPC H04L27/06 

FIELD: communication equipment.

SUBSTANCE: invention relates to communication engineering and can be used in receiving devices of communication systems. Demodulator comprises series-connected analogue-to-digital converter, multiplier, first and second conversion circuits, each of which comprises series-connected functional converter accumulating averaging adder and threshold device with threshold P_1c in first chain, threshold P_2k at the threshold device in the second circuit. Gating inputs of summators are combined and connected to "Synchronization" bus, and multiplier free input is supplied with value of coefficient V_m, numerically equal to parameter of characteristic function. According to the invention, logical circuits AND and NOR are introduced, which output is connected to the demodulator output, and the first input is connected to the second circuit threshold device output, while its second input is connected to the AND circuit output, the first input of which is connected to the first circuit threshold device output, and the second input of the AND circuit is connected to the "Case" bus.

EFFECT: technical result consists in improvement of noise immunity of discrete information transmission systems via communication channels.
