MINIMUM FREQUENCY SHIFT KEYING SIGNAL GENERATOR Russian patent published in 2022 - IPC H04L27/12 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering and can be used to generate signals with minimum frequency shift keying in systems for transmitting discrete information. The device for generating signals with minimum frequency shift keying contains the first master oscillator 1, the second master oscillator 2, the first mixer 3, the first trigger 4, the first phase manipulator 5, the second phase manipulator 6, the second trigger 7, the first element AND 8, the second element And 9 , an inverter 10, a clock generator 11, a third AND element 12, a delay element 13, a limiter amplifier 14, a second mixer 15, a frequency switch 16 and a synchronizer 17.

EFFECT: increasing the reliability of the signal generator with minimum frequency shift keying due to the guaranteed elimination of phase discontinuities of the generated signal by switching the phases of one of the oscillations with frequencies f₁ and f₂ only when the inequality of their phases is fulfilled at the next moment of frequency switching.
