L. V. Romashova, A. V. Romashov, A. N. Fomichyov · 2011
The mathematical analysis of a hybrid method of frequency synthesis is carried out, allowing theoretically to estimate level of noise components. Power spectral densities of a phase noise of an output signal of a hybrid synthesizer of frequencies are calculated. Comparison of level of the noise components received experimentally and theoretical is made.
