PyFEST - a Python code for accurate frequency estimation

The data consist of an application, namely PyFEST, written in Python language, and a file with instructions to install and use the application. It can be used to estimate the frequencies of short-time signals with high accuracy. Along with the application, examples with generated signal (single-ton, multi-tone, noisy, damped etc.) and measured signals are delivered for testing purposes. The frequencies of the harmonic components are evaluated one-by-one with high accuracy. Because the actions performed do not imply previous expertise, the results are not influenced by human intervention.本数据集包含以Python语言编写的应用程序PyFEST，以及一份该应用的安装与使用说明文档。该程序可用于高精度估算短时信号的频率。随该应用程序一同提供的，还有用于测试的各类示例信号：包括生成的单音、多音、带噪、阻尼等信号，以及实测信号。该工具可对谐波分量的频率进行逐次高精度估算。由于操作流程无需预先掌握专业知识，因此计算结果不受人工干预的影响。
