利用MATLAB GUI设计平台，用窗函数法设计FIR数字滤波器，对所给出的含有噪声的声音信号进行数字滤波处理，得到降噪的声音信号，进行时域频域分析，同时分析不同窗函数的效果。将文件解压至一个目录下，运行m文件即可使用。 读取.wav音频文件函数 ...

A Clinton County man has been charged with possessing large amounts of heroin and crack cocaine. At 6:33 a.m. March 29, trooper Zachary Andress of the Pennsylvania State Police Lehighton barracks was ...

This study offers important insights into how entorhinal and hippocampal activity support human thinking in feature spaces. It replicates hexagonal symmetry in entorhinal cortex, reports a novel three ...

本文提出了一种基于振幅的空间变迹滤波（SVA）新方法，用于抑制合成孔径雷达（SAR）数据中的旁瓣。该方法在SNAP2StaMPS工作流中，仅对振幅进行滤波，同时保留原始干涉相位，从而在保证形变测量精度的前提下，有效减少了由角反射器（ECR-C）引起的虚假永久 ...
