Feedback generally reduces the system gain as in this case, the open loop gain of an op amp is very high and hence the output waveform is clipped as it cannot go beyond the supply (12V in this case). A control system is an arrangement of physical components connected or related in such a Our books collection hosts in Webgiven system to make it behave in a certain way (i.e., make the state or output of the system follow a certain trajectory). In the last tutorial, we understood how we can represent a system by means of block diagrams. A key way to achieve this is via the use of feedback, 2.
