使用Matlab增强低振幅信号而无需更改信号的原始形状 [英] Strengthening the low amplitude signal using Matlab WITHOUT changing the original shape of the signal

问题描述

我在使用Matlab进行信号处理时遇到问题. 我想使用Matlab分析某些信号，但是信号幅度之间存在巨大差异. 问题在于，低幅度信号的形状类似于高幅度信号的形状.但是要分析该信号，我必须具有相同的范围幅度信号. 在不破坏信号形状和特性的情况下，我该如何做到这一点? 抱歉，我无法发送示例情节来清除该问题.

I have a problem in signal processing with Matlab. I would like to analyze some signal using Matlab but there is a huge difference between the amplitude of signals. The problem is that the shape of the signal in low amplitude is similar to the shape of the signal in high amplitude. but to analyse the signal, I have to have same range amplitude signal. how can I have that without destroying the shape and properties of the signal? Sorry I couldn't send an example plot to clear that.

推荐答案

类似的东西:

signal1;
signal2;

signal1=(signal1- min(signal1(:))/(max(signal1(:))-min(signal1(:)))
signal2=(signal2- min(signal2(:))/(max(signal2(:))-min(signal2(:)))
% Now both signals are 0-1 range
