DEVICE FOR RECOGNITION OF RADIO SIGNALS Russian patent published in 2009 - IPC G01R23/00 

FIELD: physics.

SUBSTANCE: invention concerns area of processing and recognition of radio signals and can be used in radio engineering devices for detection and recognition of amplitude-modulated (AM), amplitude-shift keyed (ASK), frequency-modulated (FM), frequency-shift keyed (FSK), phase-modulated (PHM) and phase-shift keyed (PHSK) radio signals. The specified technical result is reached because in the known device for recognition of the radio signals, containing the frequency detector; analysers of an instant spectrum; amplitude detectors; a clipping block; comparison blocks; analogue-code converters; the block of logic processing as a part of inverting elements and the AND elements; the phase detector as a part of the filter of the lower frequencies, the filter of the upper frequencies and the comparison block are in addition entered.

EFFECT: extension of a class of recognised radio signals.
