I am trying to analyze a DC motor but in one of my graphs I get circles on all my data points (sample time 0.001)
The only graph where this happens is after the multiplication of the voltage with a discrete transfer function. (see pictures 1, 2 and 3)
Even weirder is the fact that after a saturation the circles apear gone (see picture 4)
Does anyboy have an idea what causes the circles to appear because i don't see how the are created and they don't seem to influence the rest of my simulation
