2.8.7 Feedback Conversion

2 2
In some applications, it may be useful to convert the
feedback signal. One example of this is using a pressure
signal to provide flow feedback. Since the square root of
pressure is proportional to flow, the square root of the
pressure signal yields a value proportional to the flow. This
is shown in Figure 2.23.
