论文摘要
时间变化的分析，无论时间尺度均低于第二个变化还是缓慢变化，在高能天文学中变得越来越重要。许多复杂的工具可用于数据分析，并且在技术论文中描述了复杂的实践方面。在这里，我们介绍了所有这些技术所基于的基本概念。它旨在作为傅里叶分析的凝结入门，处理可以在其他地方进行详细研究的基本方面。它并不是要介绍用于数据分析的详细傅立叶工具，而是读者会找到理论基础以了解可用的分析技术。
The analysis of time variability, whether fast variations on time scales well below the second or slow changes over years, is becoming more and more important in high-energy astronomy. Many sophisticated tools are available for data analysis and complex practical aspects are described in technical papers. Here, we present the basic concepts upon which all these techniques are based. It is intended as a condensed primer of Fourier analysis, dealing with fundamental aspects that can be examined in detailed elsewhere. It is not intended to be a presentation of detailed Fourier tools for data analysis, but the reader will find the theoretical basis to understand available analysis techniques.
