NOISE CHARACTERISTICS OF COMBINED SIGNAL CONDITIONER ON BASIS OF ONE CIRCULAR SYSTEM WITH MIXER AND DIGITAL WAVEFORM SYNTHESIZER

N.P. Kandyrin
Annotations languages:

Principle of operation of combined signal conditioner fulfilled on basis of one circular phase locking system with mixer and digital waveform synthesizer is examined. Expression for the model of power spectrum density in combined conditioner of phase noises is given. Calculation results of combined conditioner phase noises for different output frequencies and frequencies of comparison in phase detector are reduced.
Keywords: combined conditioner, PLL, noise characteristics, phase noise
