Performance and Implementation of Frequency Measuring Equipment for Radio Signals

Abstract

A review of methods for estimating signal parameters and the synthesis of devices for estimating and measuring their frequency showed that there are a large number of different options for constructing frequency discriminators. On this basis, open and tracking meters can be implemented on various elements. Each of them brings its own specifics to the processing of radio signals in the frequency measurement channels. Such a variety of measuring elements and structures prescribes different approaches to their research, but only relatively simple devices can be analyzed analytically, although most often under significant restrictive assumptions. Others, more complex and with less stringent constraints, can be studied through computer modeling or hybrid modeling approaches. The ultimate and most preferred method for analyzing the accuracy of frequency discriminators and meters based on them should be considered an experimental study in laboratory or natural conditions, which allows obtaining the most reliable and valuable results.
