This paper discusses the operating principles and the main characteristics of a digital instrument for multifrequency signal analysis. The instrument provides real-time performance in a frequency range of 5-6 kHz with high measurement accuracy, obtained by combined windowing and interpolation of computed discrete Fourier transform (DFT) coefficients. Its hardware structure and measurement software for real-time operation are thoroughly illustrated and experimental results are given.

Abstract
This paper discusses the operating principles and the main characteristics of a digital instrument for multifrequency signal analysis. The instrument provides real-time performance in a frequency range of 5-6 kHz with high measurement accuracy, obtained by combined windowing and interpolation of computed discrete Fourier transform (DFT) coefficients. Its hardware structure and measurement software for real-time operation are thoroughly illustrated and experimental results are given.File in questo prodotto:
