A Combined Algorithm for Measuring the Frequency and Bandwidth of a Signal with Increased Accuracy

This article describes the development of an algorithm for increasing the accuracy of measuring the frequency and bandwidth of a signal in conditions of limited digital technology resources and time constraints. The purpose of the study was to apply the short-length FFT and CORDIC algorithms together. To do this, an algorithm was developed and tested on Xilinx FPGAs. As a result, an algorithm was obtained that can be used in systems where it is not possible to implement a long-length FFT, but high accuracy is required.
