摘要

提出了一种方法，可以非常准确地估计数字化信号的频谱，这些信号可以是周期性的，也可以是任意幅度、频率和相位的正弦波的组合。该算法采用插值离散傅里叶变换(DFT)。提出了矩形窗和汉宁窗的偏压消除和泄漏补偿。在个人计算机的虚拟环境中进行交互式分析。

Spectrum analysis by virtual leakage minimization

A method is presented which estimates very accurately the spectrum of digitized signals, which can be periodic, or combinations of sinusoids with arbitrary amplitudes, frequencies, and phases. The proposed algorithm uses the interpolated discrete Fourier transform (DFT). The bias removal and leakage compensation are presented for rectangular and Hanning windows. The analysis is performed interactively in virtual environment on personal computer.
