ANALYSIS OF AN AFC SYSTEM FOR AN AUTOMATIC SEARCH-TRACK RECEIVER

Abstract

The general behavior of a sampled data automatic frequency control loop for use in receiving pulsed radio frequency signals is described. A functional description of the system blocks is used to develop automatic frequency control (AFC) loop stability criteria. Tracking capabilities of the AFC loop are formulated and equations are derived to permit an estimation of frequency set errors. Design considerations are discussed. The frequency to voltage converter and the frequency control circuits are discussed in detail.
