FIELD: radio engineering, communication.SUBSTANCE: device for signal demodulation with differential phase-shift keying contains band-rejection filter 1, the output of which is connected to the input of rectifier 2, the output of which is connected to the first input of resolver 3 and through synchronising pulses shaping unit 4 to the second input of resolver 3, the output of which is the output of device, the input of band-rejection filter 1 through band pass filter 5 is connected to device input. Resolver 3 contains monostable multivibrator 6, the input of which is the input of resolver 3, and the output of monostable multivibrator 6 is connected to the first input of trigger 7, the second input of which is the second input of resolver 3, and the output of trigger 7 is the output of resolver 3. The proposed device performs signal demodulation with differential phase-shift keying.EFFECT: simplification of device structure.3 dwg |
