DEVICE FOR IDENTIFYING FM SIGNALS Russian patent published in 2015 - IPC H04B1/10 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to pulsed information receivers and can be used to detect the type of frequency modulation. The result is achieved due to that the device further includes a delay element, a fifth AND element, a third pulse counter, a first threshold element, a second NOT element, sixth, seventh, eighth, ninth and tenth threshold elements, sixth, seventh, eighth, ninth and tenth AND elements, a second flip-flop, fourth and fifth pulse counters. The listed additional components are connected to the basic components of the device for identifying FM signals in a certain manner.

EFFECT: higher efficiency of identifying FM signals with a parabolic modulation law.
