Spectrum analyzer using FFT via LabVIEW

Abstract

This paper belongs to a set of efforts aimed to improve the education of engineering in electronic and telecommunications, based on virtual equipment. It stand on a previous work called Networking Model for a Virtual Radio Frequency Laboratory (NMFLV) [1]. This proposal addresses with a specific topic in radio frequency. Plenty of analysis is performed in the frequency domain due to limits for time analysis. In order to understand this phenomenon the analyzer uses Fast Fourier Transform, its efficiency in the amount of mathematical operations, FFT is limited only by the number of samples. As it was mentioned our goal is boost the learning process, using IT infrastructure along with electronic prototypes, besides encourage students to use their pace in laboratory activities. The work introduced is performed via NMFLV system; it was designed a spectrum analyzer for undergraduate students and postgraduate students.
