Please include some more explanation this is very unclear

dheeraj bss

y=10/3*square(2*pi*10*t)+10/3 ;

why to add 10/3 in this eqation?

anyone can help me how to build coding 4 ask?

hi i have this programme and i need to demodulate this signal somemone help me plz
f1=100;f2=10;
t=0:0.0001:0.625;
% message
y=10/3*square(2*pi*10*t)+10/3 ;
%porteuse
x=10*cos(2*pi*100*t);
%signal modulé
v=y.*x ;
subplot(4,1,1);
xlabel('time');
ylabel('amplitude');
title('signal carre');
plot(t,y);
grid on;
subplot(4,1,2);
xlabel('time');
ylabel('amplitude');
title('porteuse');
plot(t,x);
grid on;
subplot(4,1,3);
xlabel('time');
ylabel('amplitude');
title('signal ask');
plot(t,v);
grid on;
snr=10; %bruit
y=awgn(v,snr,'measured')
subplot(4,1,4)
plot(t,y);
