Abstract :
In the given work the structure of the quartz oscillator with digital thermocompensation system synthesizer type is observed. Such oscillators provide high accuracy of thermocompensation and have high long-term stability. Weakness of such oscillators is the spectrum of an output signal. In paper the method of improvement of a spectrum of a target signal of such oscillators is considered, and the results of mathematical modeling confirming its efficiency are resulted.
