摘要

本文提出了算术傅里叶变换的一种扩展，它允许在任意频率下对离散时间信号进行频谱分析。该方法与非均匀离散傅里叶变换有关，在计算复杂度方面具有吸引人的特点。讨论了仿真结果和应用场景。

Um Algoritmo Aritmético para Análise Espectral Não-Uniforme

This paper presents an extension of the arithmetic Fourier transform which allows to perform the spectral analysis of a discrete-time signal in arbitrary frequencies. The pro- posed procedure, which is related to the nonuniform discrete Fourier transform, has attractive characteristics in terms of computational complexity. Results of simulations and application scenarios are discussed.
