hey guys.
attached is a negative feedback system. This is used to control the system and maintain stability. But something doesn't make sense to me.
If you look at the diagram, when the output is y(t)=4sint (as required) then the feedback signal becomes f(t)=2sint, but that means that the signal put back into the system will be zero (because i take my feedback signal and subtract it from my original signal) that means i will get zero output every now and then...doesn't seem very practical...can someone please shed some light ...
thanks
