[导读]在信号处理领域，MATLAB的FFT(快速傅里叶变换)是分析频域特性的核心工具。然而，实际应用中常遇到频谱泄漏、栅栏效应等异常现象，导致频谱分析结果失真。本文将从频谱泄漏的成因、栅栏效应的原理出发，结合MATLAB代码实例，系统阐述两种效应的解决 ...

[导读]在生物医学信号处理领域，MATLAB凭借其强大的快速傅里叶变换(FFT)功能，成为分析心电信号(ECG)和脑电信号(EEG)频域特性的核心工具。通过FFT算法，研究者能够将时域信号转换为频域分布，精准识别信号中的关键频率成分，为疾病诊断和生理机制研究提供 ...

Abstract: In this paper, we define the Windowed Octonion Quadratic Phase Fourier Transform (WOQPFT) and derive its inversion formula, including its essential properties, such as linearity, ...

This valuable study uses EEG and computational modeling to investigate hemispheric oscillatory asymmetries in unilateral spatial neglect. The work benefits from rare patient data and a careful ...

2016 was a good year for video marketing. 2017 will be extraordinary. Marketers know that video has become critical throughout the buying cycle, and sales teams are catching on as well. Brands are no ...
