Hello.
How would I make a square wave using a summation of sinusoidal signals as shown in the image below;
Thank you,
Andy.

It is actually possible to do this in about three lines of code, and no loops.
However that assignment would likely requrie a for loop.
I leave the rest to you.

I don't have to use a for loop persay, as it's a tutorial rather than an assignment - Would you be able to elaborate on the code if you have the time?
Thanks again,
Andy.

%f true
f = 0.5;
vp = 2;
N = 8;
t = 0:0.01:2;
for k = 1: length(t)
for i = 1:N
K(i,k) = (1/(2*i-1))*(vp*sin(2*pi*(2*i-1)*f*t(k)));
end
KK(k)= (4/pi)*sum(K(:,k));
end
plot(t,KK)
