Флуктуаційні характеристики перестроюваних квазігармонічних RC-автогенераторів

Abstract

This master's qualification thesis is devoted to problems of the research of fluctuation characteristics of the tunable quasi-harmonic RC-oscillators. In work approximate methods of calculations parameters, steady conditions and fluctuation characteristics of RC-oscillators are investigated. Comparative analysis of the different schemes RC-oscillators according to regime and fluctuation characteristics is carried out. Operating modes of quasi-harmonic RC-oscillators with the systems of automatic control of amplitude are considered and investigated. Operating modes and the main characteristics of the reconstructed quasi-harmonic RC-oscillators managed by tension are investigated. In the environment of circuitry modeling of Multisim™ of the National Instruments Corporation company the research of the considered schemes RC-oscillators is conducted. By the received results their comparative analysis, the certain best option is carried out.
