How many data points are gathered during favorable FP pairing to enable integration over time?

• A. 5 data points
• B. 3 data points
• C. 7 data points
• D. 9 data points

Answer: (A)

When you want to integrate a time-varying signal during a favorable FP pairing, you need enough samples to estimate the area under the curve accurately over that window. Five data points give you a window divided into four equal time steps, which lets you apply a reliable numerical integration method (such as Simpson’s rule) that uses parabolic segments for better accuracy. This setup balances capturing the signal’s shape with not overshooting the window.

With only three data points, the estimate would be coarser and less reliable. Five points are the minimum that enable a standard, more accurate integration approach over the interval, while seven or nine points would provide more detail than necessary for this particular window. Therefore, five data points are the right choice.
