Strengthening the low amplitude signal using Matlab WITHOUT changing the original shape of the signal

Question

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.

Answer 1

Something like:

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

Without more information this is all what we can offer!
