Dear Nikos
this is a example to plot the Chirp LoRa Modulation code
clc
clear all
close all
%%
t=0:0.05:40;
A=1;
omega=2;
s_t = t.^2/4;
y_t=A*cos(omega*t + s_t);
plot(t,y_t,'LineWidth',2);
set(gca,'Box','on',.....,
'FontSize', 12,.....,
'FontWeight','bold',....,
'LineWidth',1.5,.....,
'FontName','Helvetica',......,
'Color',[0.95 0.95 0.95],.....,
'XGrid','on',.....,
'YGrid','on');
xlabel('time'); ylabel('signal')
title('Chirp Signal');
