Because of the discrete sampling, the actual error and calculations will need to be
performed as shown in Figure 8-6. The value is measured at time intervals and P, I and D
calculations are based on those error samples. Since the signal value is only measured at
discrete intervals, the proportional drive is only updated at each sample.
