Annotations languages:

Mathematical analysis of noisiness phase-locked loop frequency control system with mixer in feed back circuit is conducted. Expressions for calculation power spectral density phase noises of output signal are given. The calculated noise characteristics of output signal in such system with concrete parameters are cited.
Keywords: phase noises, PLL, power spectral density
