Цифровий метод спектрального аналізу радіосигналів

Abstract

The paper presents a method of spectral analysis of radio signals based on the pre-digital processing of the sample array of the investigated signal. This makes it possible to significantly increase the resolution of determining the spectral components of radio signals and to provide a mode of operation of the means of spectral analysis of radio signals on a relatively real time scale. The structure of the digital radio spectrum analyzer has been developed, which is based on the hardware and software implementation and is characterized by high frequency resolution and minimal hardware costs.
