i have written a code to generate a square wave and to detect its both edges(positive and negative) but it won't work in that manner. pls help me to detect both edges correctly. thanks in advance
t= linspace(0,1,100);
period=0.5;
I=1;
f=0;
p=0;
i_block = 0;
for k = 1:100
t(k)
i_block(k) = mod(t(k)/period, 1) > 0.5;
if i_block(k) > 0 & i_block(k) <=1
p=p+1
else
f=f+1
end;
end;
plot(t, i_block,'r')
