Document Summary
Even though there is a ripple, the variation of the ripple remains around the same average value (~37). It is a small variation around a specific value. Intially, it varies around 37, then the temperature increases and it varies around 40, not 37. This is what happens when someone has a fever. The component that is at the blunt end affects the component on the arrow end. In this case, a change in component 1 directly leads to a change in component 2, a change in component 2 does not change anything in component 1. + sign = a change in the same direction. If component 1 gets smaller, component 2 gets smaller. Sign = a change in the opposite direction. These components are connected in a loop, if there was no connection between 1 & 3, it would be a feed forward not a feedback system. Comparing unit compares output from sensor with a set point.
