Phase locked loop combined system of voltage cotrolled oscillator

Abstract

There given the research results to help further improvement of the synchronized oscillator PLL combined systems. The main objective of the research was to develop the tracking system that provides increase of its key performance indices in tracking meters of radar location systems, radio navigation systems, communication and other wireless devices and systems of receiving and processing signals with the regular slow-varying frequency component,referred as the Doppler signals, generated during normal-mode interference.
