Hello!! I am plotting an easy sin function but I dont understand why when the variable delta is 0.2 0.4 0.6 and so on I get a perfect sin, but on the other hand when I plot it with delta 0.1 0.3 0.5 I get a diffrent plot. I think has to be something with the modulation. Here is goes the code

f=linspace(0.1,10e6);

delta=0.2;

y=sin(pi*f.*delta);

plot(f,y)

Thanks a lot Nicolas
