Situation, if only set up the signal intensity of a feedback signal and the relation of the signal intensity of output signal by overall trend
Curve model, then can cause larger error, how the signal intensity of the first input signal is divided into multiple intervals.
Preferably zoning ordinance is：For the first input signal of P predetermined signal strength, signal intensity is divided into P-1
Individual interval (often two neighboring signal intensity is divided into an interval).The first of three predetermined signal strength as shown in table 2 below
Input signal, two after division interval is respectively (40≤RGI<65), (65≤RGI≤76).

Relation curve.
In this example, RGI=65 is belonging to interval (65≤RGI≤76), but due to interval (40≤RGI<65)
In only one group of data, and RGI=65, as interval separation, can determine Y=in conjunction with the corresponding data of RGI=40 jointly
