The Arduino ecosystem is an amazing learning tool, but even those of us who love it admit that even the simplified C Arduino uses isn’t the ideal teaching language. Those of us who remember ...

补零是一种有效的技术，可以改善 FFT结果的可视化效果，并可能加快计算速度。然而，重要的是要理解，它不会提高原始信号的基频分辨率，如果使用不当，可能会引入伪影。快速傅里叶变换 (FFT)中为什么要补零？

The Fast Fourier Transform (FFT) is a foundational algorithm widely used in fields like digital signal processing and machine learning. While High-Level Synthesis (HLS) tools have boosted the ...

In this paper, we analyze the working principle of an arduino. These days many people try to use the arduino because it makes things easier due to the simplified version of C++ and the already made ...

01 FFT简介 快速傅里叶变换 (Fast Fourier Transform，FFT), 即利用计算机计算离散傅里叶变换（DFT)的高效、快速计算方法的统称，简称FFT。DFT是实现了从频域（频域分析往往比时域分析更优越）对信号与系统进行分析。然而，随着序列长度的增加，计算量也显著增加，对于计算机而言，处理时间就越长 ...
