Help Plot EEG wave
Show older comments
I have an eeg signal and i am trying to plot it time vs amplitude, for some reason it is clipping and i dont know how to fix it, changing the ylim only changes the axis, please help
here is the code
close all; clear all; clc;
fs = 512
T = 1/fs;% sampling rate or frequency
load 'base' % contains eeg1 and fs
tx =[0:length(data)-1]/fs;% Make time axis for EEG signal
figure; subplot (211), plot(tx,data); xlabel('Time (s)'), ylabel('Amplitude (uV)'), title('Original EEG signal'); %EEG waveform
subplot(212), plot(tx,data);
xlabel('Time (s)'), ylabel('Amplitude (uV)'), title('Zoom into original EEG signal at 1 to 2 seconds'), xlim([1,2]) % Used to zoom in on single ECG waveformfigure;
%The mean of the PSDs of xl
mean_EEGsig = mean(data)
max_value=max(data)
mean_value=mean(data)
threshold=(max_value-mean_value)/2;

Unfortunately, you ‘railed’ the amplifier. You cannot recover the lost data.
